<span class="sd">Method ``link_token``</span>
<span class="sd">---------------------</span>
<span class="sd">The ``link_token`` method evaluates a request as :py:obj:`suspicious</span>
<span class="sd">&lt;is_suspicious&gt;` if the URL ``/client&lt;token&gt;.css`` is not requested by the</span>
<span class="sd">client. By adding a random component (the token) in the URL, a bot can not send</span>
<span class="sd">a ping by request a static URL.</span>
<span class="sd">.. note::</span>
<span class="sd"> This method requires a redis DB and needs a HTTP X-Forwarded-For_ header.</span>
<span class="sd">To get in use of this method a flask URL route needs to be added:</span>
<span class="sd">.. code:: python</span>
<span class="sd"> @app.route(&#39;/client&lt;token&gt;.css&#39;, methods=[&#39;GET&#39;, &#39;POST&#39;])</span>
<span class="sd"> def client_token(token=None):</span>
<span class="sd"> link_token.ping(request, token)</span>
<span class="sd"> return Response(&#39;&#39;, mimetype=&#39;text/css&#39;)</span>
<span class="sd">And in the HTML template from flask a stylesheet link is needed (the value of</span>
<span class="sd">``link_token`` comes from :py:obj:`get_token`):</span>
<span class="sd">.. code:: html</span>
<span class="sd"> &lt;link rel=&quot;stylesheet&quot;</span>

<span class="sd">Brave regions</span>
<span class="sd">=============</span>
<span class="sd">Brave uses two-digit tags for the regions like ``ca`` while SearXNG deals with</span>
<span class="sd">locales. To get a mapping, all *officatl de-facto* languages of the Brave</span>
<span class="sd">region are mapped to regions in SearXNG (see :py:obj:`babel</span>

<span class="sd"> The language (aka region) support of Brave&#39;s index is limited to very basic</span>

<span class="sd">&quot;&quot;&quot;With *command engines* administrators can run engines to integrate arbitrary</span>
<span class="sd">shell commands.</span>
<span class="sd">.. attention::</span>
<span class="sd"> When creating and enabling a ``command`` engine on a public instance, you</span>
<span class="sd"> must be careful to avoid leaking private data.</span>
<span class="sd">The easiest solution is to limit the access by setting ``tokens`` as described</span>
<span class="sd">in section :ref:`private engines`. The engine base is flexible. Only your</span>
<span class="sd">imagination can limit the power of this engine (and maybe security concerns).</span>
<span class="sd">Configuration</span>
<span class="sd">=============</span>
<span class="sd">The following options are available:</span>
<span class="sd">``command``:</span>
<span class="sd"> A comma separated list of the elements of the command. A special token</span>
<span class="sd"> ``{{QUERY}}`` tells where to put the search terms of the user. Example:</span>
<span class="sd"> .. code:: yaml</span>
<span class="sd"> [&#39;ls&#39;, &#39;-l&#39;, &#39;-h&#39;, &#39;{{QUERY}}&#39;]</span>
<span class="sd">``delimiter``:</span>
<span class="sd"> A mapping containing a delimiter ``char`` and the *titles* of each element in</span>
<span class="sd"> ``keys``.</span>
<span class="sd">``parse_regex``:</span>
<span class="sd"> A dict containing the regular expressions for each result key.</span>
<span class="sd">``query_type``:</span>
<span class="sd"> The expected type of user search terms. Possible values: ``path`` and</span>
<span class="sd"> ``enum``.</span>
<span class="sd"> ``path``:</span>
<span class="sd"> Checks if the user provided path is inside the working directory. If not,</span>
<span class="sd"> the query is not executed.</span>
<span class="sd"> ``enum``:</span>
<span class="sd"> Is a list of allowed search terms. If the user submits something which is</span>
<span class="sd"> not included in the list, the query returns an error.</span>
<span class="sd">``query_enum``:</span>
<span class="sd"> A list containing allowed search terms if ``query_type`` is set to ``enum``.</span>
<span class="sd">``working_dir``:</span>
<span class="sd"> The directory where the command has to be executed. Default: ``./``.</span>
<span class="sd">``result_separator``:</span>
<span class="sd"> The character that separates results. Default: ``\\n``.</span>
<span class="sd">Example</span>
<span class="sd">=======</span>
<span class="sd">The example engine below can be used to find files with a specific name in the</span>
<span class="sd">configured working directory:</span>
<span class="sd">.. code:: yaml</span>
<span class="sd"> - name: find</span>
<span class="sd"> engine: command</span>
<span class="sd"> command: [&#39;find&#39;, &#39;.&#39;, &#39;-name&#39;, &#39;{{QUERY}}&#39;]</span>
<span class="sd"> query_type: path</span>
<span class="sd"> shortcut: fnd</span>
<span class="sd"> delimiter:</span>
<span class="sd"> chars: &#39; &#39;</span>
<span class="sd"> keys: [&#39;line&#39;]</span>

<span class="sd">~~~~~~~~~~~~~~~~~~~~~~~~~~~~~</span>
<span class="sd">The `DDG-API &lt;https://duckduckgo.com/api&gt;`__ is no longer documented but from</span>
<span class="sd">reverse engineering we can see that some services (e.g. instant answers) still</span>
<span class="sd">in use from the DDG search engine.</span>
<span class="sd">As far we can say the *instant answers* API does not support languages, or at</span>
<span class="sd">least we could not find out how language support should work. It seems that</span>
<span class="sd">most of the features are based on English terms.</span>

<span class="c1"># gl parameter: (mandatory by Geeogle News)</span>
<span class="c1"># The gl parameter value is a two-letter country code. For WebSearch</span>

<span class="c1"># matches the parameter value. See the Country Codes section for a list of</span>
<span class="c1"># valid values.</span>
<span class="c1"># Specifying a gl parameter value in WebSearch requests should improve the</span>
<span class="c1"># relevance of results. This is particularly true for international</span>
<span class="c1"># customers and, even more specifically, for customers in English-speaking</span>
<span class="c1"># countries other than the United States.</span>

<span class="sd">&quot;&quot;&quot;Torznab_ is an API specification that provides a standardized way to query</span>
<span class="sd">torrent site for content. It is used by a number of torrent applications,</span>
<span class="sd">including Prowlarr_ and Jackett_.</span>
<span class="sd">Using this engine together with Prowlarr_ or Jackett_ allows you to search</span>
<span class="sd">a huge number of torrent sites which are not directly supported.</span>
<span class="sd">Configuration</span>
<span class="sd">=============</span>
<span class="sd">The engine has the following settings:</span>
<span class="sd">``base_url``:</span>
<span class="sd"> Torznab endpoint URL.</span>
<span class="sd">``api_key``:</span>
<span class="sd"> The API key to use for authentication.</span>
<span class="sd">``torznab_categories``:</span>
<span class="sd"> The categories to use for searching. This is a list of category IDs. See</span>
<span class="sd"> Prowlarr-categories_ or Jackett-categories_ for more information.</span>
<span class="sd">``show_torrent_files``:</span>
<span class="sd"> Whether to show the torrent file in the search results. Be carful as using</span>
<span class="sd"> this with Prowlarr_ or Jackett_ leaks the API key. This should be used only</span>
<span class="sd"> if you are querying a Torznab endpoint without authentication or if the</span>
<span class="sd"> instance is private. Be aware that private trackers may ban you if you share</span>
<span class="sd"> the torrent file. Defaults to ``false``.</span>
<span class="sd">``show_magnet_links``:</span>
<span class="sd"> Whether to show the magnet link in the search results. Be aware that private</span>
<span class="sd"> trackers may ban you if you share the magnet link. Defaults to ``true``.</span>

<span class="sd">&quot;&quot;&quot;This module implements the Wikipedia engine. Some of this implementations</span>
<span class="sd">are shared by other engines:</span>
<span class="sd">- :ref:`wikidata engine`</span>
<span class="sd">The list of supported languages is :py:obj:`fetched &lt;fetch_wikimedia_traits&gt;` from</span>
<span class="sd">the article linked by :py:obj:`list_of_wikipedias`.</span>
<span class="sd">Unlike traditional search engines, wikipedia does not support one Wikipedia for</span>
<span class="sd">all languages, but there is one Wikipedia for each supported language. Some of</span>
<span class="sd">these Wikipedias have a LanguageConverter_ enabled</span>
<span class="sd">(:py:obj:`rest_v1_summary_url`).</span>
<span class="sd">A LanguageConverter_ (LC) is a system based on language variants that</span>
<span class="sd">automatically converts the content of a page into a different variant. A variant</span>
<span class="sd">is mostly the same language in a different script.</span>
<span class="sd">- `Wikipedias in multiple writing systems`_</span>
<span class="sd">- `Automatic conversion between traditional and simplified Chinese characters`_</span>
<span class="sd">PR-2554_:</span>
<span class="sd"> The Wikipedia link returned by the API is still the same in all cases</span>
<span class="sd"> (`https://zh.wikipedia.org/wiki/出租車`_) but if your browser&#39;s</span>
<span class="sd"> ``Accept-Language`` is set to any of ``zh``, ``zh-CN``, ``zh-TW``, ``zh-HK``</span>
<span class="sd"> or .. Wikipedia&#39;s LC automatically returns the desired script in their</span>
<span class="sd"> web-page.</span>
<span class="sd"> - You can test the API here: https://reqbin.com/gesg2kvx</span>

<span class="sd">To support Wikipedia&#39;s LanguageConverter_, a SearXNG request to Wikipedia uses</span>
<span class="sd">:py:obj:`get_wiki_params` and :py:obj:`wiki_lc_locale_variants&#39; in the</span>
<span class="sd">:py:obj:`fetch_wikimedia_traits` function.</span>
<span class="sd">To test in SearXNG, query for ``!wp 出租車`` with each of the available Chinese</span>
<span class="sd">options:</span>

<span class="sd">&quot;&quot;&quot;`Z-Library`_ (abbreviated as z-lib, formerly BookFinder) is a shadow library</span>
<span class="sd">project for file-sharing access to scholarly journal articles, academic texts</span>
<span class="sd">and general-interest books. It began as a mirror of Library Genesis, from which</span>
<span class="sd">most of its books originate.</span>
<span class="sd">.. _Z-Library: https://zlibrary-global.se/</span>
<span class="sd">Configuration</span>
<span class="sd">=============</span>
<span class="sd">The engine has the following additional settings:</span>
<span class="sd">- :py:obj:`zlib_year_from`</span>
<span class="sd">- :py:obj:`zlib_year_to`</span>
<span class="sd">- :py:obj:`zlib_ext`</span>
<span class="sd">With this options a SearXNG maintainer is able to configure **additional**</span>
<span class="sd">engines for specific searches in Z-Library. For example a engine to search</span>
<span class="sd">only for EPUB from 2010 to 2020.</span>
<span class="sd">.. code:: yaml</span>

===============================
Answer CAPTCHA from server's IP
===============================
With a SSH tunnel we can send requests from server's IP and solve a CAPTCHA that
blocks requests from this IP. If your SearXNG instance is hosted at
``example.org`` and your login is ``user`` you can setup a proxy simply by
:man:`ssh`:
.. code:: bash
# SOCKS server: socks://127.0.0.1:8080
$ ssh -q -N -D 8080 user@example.org
The ``socks://localhost:8080`` from above can be tested by:
.. tabs::
.. group-tab:: server's IP
.. code:: bash
$ curl -x socks://127.0.0.1:8080 http://ipecho.net/plain
n.n.n.n
.. group-tab:: desktop's IP
.. code:: bash
$ curl http://ipecho.net/plain
x.x.x.x
In the settings of the WEB browser open the *"Network Settings"* and setup a
proxy on ``SOCKS5 127.0.0.1:8080`` (see screenshot below). In the WEB browser
check the IP from the server is used:
- http://ipecho.net/plain
Now open the search engine that blocks requests from your server's IP. If you
have `issues with the qwant engine
<https://github.com/searxng/searxng/issues/2011#issuecomment-1553317619>`__,
solve the CAPTCHA from `qwant.com <https://www.qwant.com/>`__.

.. tabs::
.. group-tab:: Firefox
.. kernel-figure:: answer-captcha/ffox-setting-proxy-socks.png
:alt: FFox proxy on SOCKS5, 127.0.0.1:8080
Firefox's network settings
.. admonition:: :man:`ssh` manual:
-D [bind_address:]port
Specifies a local “dynamic” application-level port forwarding. This works
by allocating a socket to listen to port on the local side .. Whenever a
connection is made to this port, the connection is forwarded over the
secure channel, and the application protocol is then used to determine
where to connect to from the remote machine .. ssh will act as a SOCKS
server ..
-N
Do not execute a remote command. This is useful for just forwarding ports.

Embed search bar
================
The search bar can be embedded into websites. Just paste the example into the
HTML of the site. URL of the SearXNG instance and values are customizable.
.. code:: html

<!-- search --> <input type="text" name="q" />

To get best results from build, it's recommend to install additional packages on
build hosts (see :ref:`searxng.sh`).
.. _searxng.sh install buildhost:
Build and Development tools
===========================
To Install tools used by build and development tasks in once:
.. tabs::
.. group-tab:: SearXNG's development tools
.. code:: sh
$ sudo -H ./utils/searxng.sh install buildhost
This will install packages needed by SearXNG:
.. kernel-include:: $DOCS_BUILD/includes/searxng.rst
:start-after: START distro-packages
:end-before: END distro-packages

.. sidebar:: Sphinx build needs
- ImageMagick_
- Graphviz_
- XeTeX_
- dvisvgm_
Most of the sphinx requirements are installed from :origin:`setup.py` and the
docs can be build from scratch with ``make docs.html``. For better math and
image processing additional packages are needed. The XeTeX_ needed not only for
PDF creation, it's also needed for :ref:`math` when HTML output is build.
To be able to do :ref:`sphinx:math-support` without CDNs, the math are rendered
as images (``sphinx.ext.imgmath`` extension).
Here is the extract from the :origin:`docs/conf.py` file, setting math renderer
to ``imgmath``:
.. literalinclude:: ../conf.py
:language: python
:start-after: # sphinx.ext.imgmath setup
:end-before: # sphinx.ext.imgmath setup END
If your docs build (``make docs.html``) shows warnings like this::
WARNING: dot(1) not found, for better output quality install \
graphviz from https://www.graphviz.org
..
WARNING: LaTeX command 'latex' cannot be run (needed for math \
display), check the imgmath_latex setting
you need to install additional packages on your build host, to get better HTML
output (:ref:`install buildhost <searxng.sh install buildhost>`).

This section explains how to set up a SearXNG instance using the HTTP server Apache_.
If you did use the :ref:`installation scripts` and do not have any special preferences
you can install the :ref:`SearXNG site <apache searxng site>` using
:ref:`searxng.sh <searxng.sh overview>`:
.. code:: bash
$ sudo -H ./utils/searxng.sh install apache
If you have special interests or problems with setting up Apache, the following
section might give you some guidance.

The Apache HTTP server
======================
If Apache_ is not installed, install it now. If apache_ is new to you, the
`Getting Started`_, `Configuration Files`_ and `Terms Used to Describe
Directives`_ documentation gives first orientation. There is also a list of
`Apache directives`_ *to keep in the pocket*.
.. tabs::
.. group-tab:: Ubuntu / debian
.. code:: bash
sudo -H apt-get install apache2
.. group-tab:: Arch Linux
.. code:: bash
sudo -H pacman -S apache
sudo -H systemctl enable httpd
sudo -H systemctl start http
.. group-tab:: Fedora / RHEL
.. code:: bash
sudo -H dnf install httpd
sudo -H systemctl enable httpd
sudo -H systemctl start httpd
Now at http://localhost you should see some kind of *Welcome* or *Test* page.
How this default site is configured, depends on the linux distribution
(compare `Apache directives`_).
.. tabs::
.. group-tab:: Ubuntu / debian
.. code:: bash
less /etc/apache2/sites-enabled/000-default.conf
In this file, there is a line setting the `DocumentRoot`_ directive:
.. code:: apache
DocumentRoot /var/www/html
And the *welcome* page is the HTML file at ``/var/www/html/index.html``.
.. group-tab:: Arch Linux
.. code:: bash
less /etc/httpd/conf/httpd.conf
In this file, there is a line setting the `DocumentRoot`_ directive:
.. code:: apache
DocumentRoot "/srv/http"
<Directory "/srv/http">
Options Indexes FollowSymLinks
AllowOverride None
Require all granted
</Directory>
The *welcome* page of Arch Linux is a page showing the directory located
at ``DocumentRoot``. This *directory* page is generated by the Module
`mod_autoindex <https://httpd.apache.org/docs/2.4/mod/mod_autoindex.html>`_:
.. code:: apache
LoadModule autoindex_module modules/mod_autoindex.so
...
Include conf/extra/httpd-autoindex.conf
.. group-tab:: Fedora / RHEL
.. code:: bash
less /etc/httpd/conf/httpd.conf
In this file, there is a line setting the ``DocumentRoot`` directive:
.. code:: apache
DocumentRoot "/var/www/html"
...
<Directory "/var/www">
AllowOverride None
# Allow open access:
Require all granted
</Directory>
On fresh installations, the ``/var/www`` is empty and the *default
welcome page* is shown, the configuration is located at::
less /etc/httpd/conf.d/welcome.conf
.. _Debian's Apache layout:
Debian's Apache layout
----------------------
Be aware, Debian's Apache layout is quite different from the standard Apache
configuration. For details look at the apache2.README.Debian_
(``/usr/share/doc/apache2/README.Debian.gz``). Some commands you should know on
Debian:
* :man:`apache2ctl`: Apache HTTP server control interface
* :man:`a2enmod`, :man:`a2dismod`: switch on/off modules
* :man:`a2enconf`, :man:`a2disconf`: switch on/off configurations
* :man:`a2ensite`, :man:`a2dissite`: switch on/off sites
.. _apache modules:
Apache modules
--------------
To load additional modules, in most distributions you have to un-comment the
lines with the corresponding LoadModule_ directive, except in :ref:`Debian's
Apache layout`.
.. tabs::
.. group-tab:: Ubuntu / debian
:ref:`Debian's Apache layout` uses :man:`a2enmod` and :man:`a2dismod` to
activate or disable modules:
.. code:: bash
sudo -H a2enmod ssl
sudo -H a2enmod headers
sudo -H a2enmod proxy
sudo -H a2enmod proxy_http
sudo -H a2enmod proxy_uwsgi
.. group-tab:: Arch Linux
In the ``/etc/httpd/conf/httpd.conf`` file, activate LoadModule_
directives:
.. code:: apache
LoadModule ssl_module modules/mod_ssl.so
LoadModule headers_module modules/mod_headers.so
LoadModule proxy_module modules/mod_proxy.so
LoadModule proxy_http_module modules/mod_proxy_http.so
LoadModule proxy_uwsgi_module modules/mod_proxy_uwsgi.so
.. group-tab:: Fedora / RHEL
In the ``/etc/httpd/conf/httpd.conf`` file, activate LoadModule_
directives:
.. code:: apache
LoadModule ssl_module modules/mod_ssl.so
LoadModule headers_module modules/mod_headers.so
LoadModule proxy_module modules/mod_proxy.so
LoadModule proxy_http_module modules/mod_proxy_http.so
LoadModule proxy_uwsgi_module modules/mod_proxy_uwsgi.so
.. _apache sites:
Apache sites
------------
.. tabs::
.. group-tab:: Ubuntu / debian
In :ref:`Debian's Apache layout` you create a ``searxng.conf`` with the
``<Location /searxng >`` directive and save this file in the *sites
available* folder at ``/etc/apache2/sites-available``. To enable the
``searxng.conf`` use :man:`a2ensite`:
.. code:: bash
sudo -H a2ensite searxng.conf
.. group-tab:: Arch Linux
In the ``/etc/httpd/conf/httpd.conf`` file add a IncludeOptional_
directive:
.. code:: apache
IncludeOptional sites-enabled/*.conf
Create two folders, one for the *available sites* and one for the *enabled sites*:
.. code:: bash
mkdir -p /etc/httpd/sites-available
mkdir -p /etc/httpd/sites-enabled
Create configuration at ``/etc/httpd/sites-available`` and place a
symlink to ``sites-enabled``:
.. code:: bash
sudo -H ln -s /etc/httpd/sites-available/searxng.conf \
/etc/httpd/sites-enabled/searxng.conf
.. group-tab:: Fedora / RHEL
In the ``/etc/httpd/conf/httpd.conf`` file add a IncludeOptional_
directive:
.. code:: apache
IncludeOptional sites-enabled/*.conf
Create two folders, one for the *available sites* and one for the *enabled sites*:
.. code:: bash
mkdir -p /etc/httpd/sites-available
mkdir -p /etc/httpd/sites-enabled
Create configuration at ``/etc/httpd/sites-available`` and place a
symlink to ``sites-enabled``:
.. code:: bash
sudo -H ln -s /etc/httpd/sites-available/searxng.conf \
/etc/httpd/sites-enabled/searxng.conf
.. _apache searxng site:
Apache's SearXNG site
=====================
.. _mod_uwsgi: https://uwsgi-docs.readthedocs.io/en/latest/Apache.html#mod-uwsgi
.. sidebar:: uWSGI
Use mod_proxy_uwsgi_ / don't use the old mod_uwsgi_ anymore.
To proxy the incoming requests to the SearXNG instance Apache needs the
mod_proxy_ module (:ref:`apache modules`).
.. sidebar:: HTTP headers
With ProxyPreserveHost_ the incoming ``Host`` header is passed to the proxied
host.
Depending on what your SearXNG installation is listening on, you need a http
mod_proxy_http_) or socket (mod_proxy_uwsgi_) communication to upstream.
The :ref:`installation scripts` installs the :ref:`reference setup
<use_default_settings.yml>` and a :ref:`uwsgi setup` that listens on a socket by default.
You can install and activate your own ``searxng.conf`` like shown in
:ref:`apache sites`.
.. tabs::
.. group-tab:: socket
.. kernel-include:: $DOCS_BUILD/includes/searxng.rst
:start-after: START apache socket
:end-before: END apache socket
.. group-tab:: http
.. kernel-include:: $DOCS_BUILD/includes/searxng.rst
:start-after: START apache http
:end-before: END apache http
.. _restart apache:
Restart service:
.. tabs::
.. group-tab:: Ubuntu / debian
.. code:: bash
sudo -H systemctl restart apache2
sudo -H service uwsgi restart searxng
.. group-tab:: Arch Linux
.. code:: bash
sudo -H systemctl restart httpd
sudo -H systemctl restart uwsgi@searxng
.. group-tab:: Fedora / RHEL
.. code:: bash
sudo -H systemctl restart httpd
sudo -H touch /etc/uwsgi.d/searxng.ini
disable logs
============
For better privacy you can disable Apache logs. In the examples above activate
one of the lines and `restart apache`_:
.. code:: apache
SetEnvIf Request_URI "/searxng" dontlog
# CustomLog /dev/null combined env=dontlog
The ``CustomLog`` directive disables logs for the entire (virtual) server, use it
when the URL of the service does not have a path component (``/searxng``), so when
SearXNG is located at root (``/``).

----
Get Docker
==========
If you plan to build and maintain a docker image by yourself, make sure you have
`Docker installed <https://docs.docker.com/get-docker/>`_. On Linux don't
forget to add your user to the docker group (log out and log back in so that
your group membership is re-evaluated):
.. code:: sh
$ sudo usermod -a -G docker $USER
searxng/searxng
===============
.. sidebar:: ``docker run``
- `-\-rm <https://docs.docker.com/engine/reference/run/#clean-up---rm>`__
automatically clean up when container exits
- `-d <https://docs.docker.com/engine/reference/run/#detached--d>`__ start
detached container
- `-v <https://docs.docker.com/engine/reference/run/#volume-shared-filesystems>`__
mount volume ``HOST:CONTAINER``
The docker image is based on :origin:`Dockerfile` and available from
`searxng/searxng @dockerhub`_. Using the docker image is quite easy, for
instance you can pull the `searxng/searxng @dockerhub`_ image and deploy a local
instance using `docker run <https://docs.docker.com/engine/reference/run/>`_:
.. code:: sh
$ mkdir my-instance
$ cd my-instance
$ export PORT=8080
$ docker pull searxng/searxng
$ docker run --rm \
-d -p ${PORT}:8080 \
-v "${PWD}/searxng:/etc/searxng" \
-e "BASE_URL=http://localhost:$PORT/" \
-e "INSTANCE_NAME=my-instance" \
searxng/searxng
2f998.... # container's ID
Open your WEB browser and visit the URL:
.. code:: sh
$ xdg-open "http://localhost:$PORT"
Inside ``${PWD}/searxng``, you will find ``settings.yml`` and ``uwsgi.ini``. You
can modify these files according to your needs and restart the Docker image.
.. code:: sh
$ docker container restart 2f998
Use command ``container ls`` to list running containers, add flag `-a
<https://docs.docker.com/engine/reference/commandline/container_ls>`__ to list
exited containers also. With ``container stop`` a running container can be
stoped. To get rid of a container use ``container rm``:
.. code:: sh
$ docker container ls
CONTAINER ID IMAGE COMMAND CREATED ...
2f998d725993 searxng/searxng "/sbin/tini -- /usr/…" 7 minutes ago ...
$ docker container stop 2f998
$ docker container rm 2f998
.. sidebar:: Warning
This might remove all docker items, not only those from SearXNG.
If you won't use docker anymore and want to get rid of all containers & images
use the following *prune* command:
.. code:: sh
$ docker stop $(docker ps -aq) # stop all containers
$ docker system prune # make some housekeeping
$ docker rmi -f $(docker images -q) # drop all images
shell inside container
----------------------
.. sidebar:: Bashism
- `A tale of two shells: bash or dash <https://lwn.net/Articles/343924/>`_
- `How to make bash scripts work in dash <http://mywiki.wooledge.org/Bashism>`_
- `Checking for Bashisms <https://dev.to/bowmanjd/writing-bash-scripts-that-are-not-only-bash-checking-for-bashisms-and-testing-with-dash-1bli>`_
Like in many other distributions, Alpine's `/bin/sh
<https://wiki.ubuntu.com/DashAsBinSh>`__ is :man:`dash`. Dash is meant to be
`POSIX-compliant <https://pubs.opengroup.org/onlinepubs/9699919799>`__.
Compared to debian, in the Alpine image :man:`bash` is not installed. The
:origin:`dockerfiles/docker-entrypoint.sh` script is checked *against dash*
(``make tests.shell``).
To open a shell inside the container:
.. code:: sh
$ docker exec -it 2f998 sh
Build the image
===============
It's also possible to build SearXNG from the embedded :origin:`Dockerfile`::
$ git clone https://github.com/searxng/searxng.git
$ cd searxng
$ make docker.build
...

The nginx HTTP server
=====================
If nginx_ is not installed, install it now.
.. tabs::
.. group-tab:: Ubuntu / debian
.. code:: bash
sudo -H apt-get install nginx
.. group-tab:: Arch Linux
.. code-block:: sh
sudo -H pacman -S nginx-mainline
sudo -H systemctl enable nginx
sudo -H systemctl start nginx
.. group-tab:: Fedora / RHEL
.. code-block:: sh
sudo -H dnf install nginx
sudo -H systemctl enable nginx
sudo -H systemctl start nginx
Now at http://localhost you should see a *Welcome to nginx!* page, on Fedora you
see a *Fedora Webserver - Test Page*. The test page comes from the default
`nginx server configuration`_. How this default site is configured,
depends on the linux distribution:
.. tabs::
.. group-tab:: Ubuntu / debian
.. code:: bash
less /etc/nginx/nginx.conf
There is one line that includes site configurations from:
.. code:: nginx
include /etc/nginx/sites-enabled/*;
.. group-tab:: Arch Linux
.. code-block:: sh
less /etc/nginx/nginx.conf
There is a configuration section named ``server``:
.. code-block:: nginx
server {
listen 80;
server_name localhost;
# ...
}
.. group-tab:: Fedora / RHEL
.. code-block:: sh
less /etc/nginx/nginx.conf
There is one line that includes site configurations from:
.. code:: nginx
include /etc/nginx/conf.d/*.conf;
.. _nginx searxng site:
NGINX's SearXNG site
====================
Now you have to create a configuration file (``searxng.conf``) for the SearXNG
site. If nginx_ is new to you, the `nginx beginners guide`_ is a good starting
point and the `Getting Started wiki`_ is always a good resource *to keep in the
pocket*.
Depending on what your SearXNG installation is listening on, you need a http or socket
communication to upstream.
.. tabs::
.. group-tab:: socket
.. kernel-include:: $DOCS_BUILD/includes/searxng.rst
:start-after: START nginx socket
:end-before: END nginx socket
.. group-tab:: http
.. kernel-include:: $DOCS_BUILD/includes/searxng.rst
:start-after: START nginx http
:end-before: END nginx http
The :ref:`installation scripts` installs the :ref:`reference setup
<use_default_settings.yml>` and a :ref:`uwsgi setup` that listens on a socket by default.
.. tabs::
.. group-tab:: Ubuntu / debian
Create configuration at ``/etc/nginx/sites-available/`` and place a
symlink to ``sites-enabled``:
.. code:: bash
sudo -H ln -s /etc/nginx/sites-available/searxng.conf \
/etc/nginx/sites-enabled/searxng.conf
.. group-tab:: Arch Linux
In the ``/etc/nginx/nginx.conf`` file, in the ``server`` section add a
`include <https://nginx.org/en/docs/ngx_core_module.html#include>`_
directive:
.. code:: nginx
server {
# ...
include /etc/nginx/default.d/*.conf;
# ...
}
Create two folders, one for the *available sites* and one for the *enabled sites*:
.. code:: bash
mkdir -p /etc/nginx/default.d
mkdir -p /etc/nginx/default.apps-available
Create configuration at ``/etc/nginx/default.apps-available`` and place a
symlink to ``default.d``:
.. code:: bash
sudo -H ln -s /etc/nginx/default.apps-available/searxng.conf \
/etc/nginx/default.d/searxng.conf
.. group-tab:: Fedora / RHEL
Create a folder for the *available sites*:
.. code:: bash
mkdir -p /etc/nginx/default.apps-available
Create configuration at ``/etc/nginx/default.apps-available`` and place a
symlink to ``conf.d``:
.. code:: bash
sudo -H ln -s /etc/nginx/default.apps-available/searxng.conf \
/etc/nginx/conf.d/searxng.conf
Restart services:
.. tabs::
.. group-tab:: Ubuntu / debian
.. code:: bash
sudo -H systemctl restart nginx
sudo -H service uwsgi restart searxng
.. group-tab:: Arch Linux
.. code:: bash
sudo -H systemctl restart nginx
sudo -H systemctl restart uwsgi@searxng
.. group-tab:: Fedora / RHEL
.. code:: bash
sudo -H systemctl restart nginx
sudo -H touch /etc/uwsgi.d/searxng.ini
Disable logs
============
For better privacy you can disable nginx logs in ``/etc/nginx/nginx.conf``.
.. code:: nginx
http {
# ...
access_log /dev/null;
error_log /dev/null;
# ...
}

.. _installation scripts:
===================
Installation Script
===================
.. sidebar:: Update the OS first!
To avoid unwanted side effects, update your OS before installing SearXNG.
The following will install a setup as shown in :ref:`the reference architecture
<arch public>`. First you need to get a clone of the repository. The clone is only needed for
the installation procedure and some maintenance tasks.
.. sidebar:: further read
- :ref:`toolboxing`
Jump to a folder that is readable by *others* and start to clone SearXNG,
alternatively you can create your own fork and clone from there.
.. code:: bash
$ cd ~/Downloads
$ git clone https://github.com/searxng/searxng.git searxng
$ cd searxng
.. sidebar:: further read
- :ref:`inspect searxng`
To install a SearXNG :ref:`reference setup <use_default_settings.yml>`
including a :ref:`uWSGI setup <architecture uWSGI>` as described in the
:ref:`installation basic` and in the :ref:`searxng uwsgi` section type:
.. code:: bash
$ sudo -H ./utils/searxng.sh install all
.. attention::
For the installation procedure, use a *sudoer* login to run the scripts. If
you install from ``root``, take into account that the scripts are creating a
``searxng`` user. In the installation procedure this new created user does
need to have read access to the cloned SearXNG repository, which is not the case if you clone
it into a folder below ``/root``!
.. sidebar:: further read
- :ref:`update searxng`
.. _caddy: https://hub.docker.com/_/caddy
When all services are installed and running fine, you can add SearXNG to your
HTTP server. We do not have any preferences regarding the HTTP server, you can use
whatever you prefer.
We use caddy in our :ref:`docker image <installation docker>` and we have
implemented installation procedures for:
- :ref:`installation nginx`
- :ref:`installation apache`

Install SearXNG & dependencies
==============================
Start a interactive shell from new created user and clone SearXNG:
.. kernel-include:: $DOCS_BUILD/includes/searxng.rst
:start-after: START clone searxng
:end-before: END clone searxng
In the same shell create *virtualenv*:
.. kernel-include:: $DOCS_BUILD/includes/searxng.rst
:start-after: START create virtualenv
:end-before: END create virtualenv
To install SearXNG's dependencies, exit the SearXNG *bash* session you opened above
and start a new one. Before installing, check if your *virtualenv* was sourced
from the login (*~/.profile*):
.. kernel-include:: $DOCS_BUILD/includes/searxng.rst
:start-after: START manage.sh update_packages
:end-before: END manage.sh update_packages
.. tip::
Open a second terminal for the configuration tasks and leave the ``(searx)$``
terminal open for the tasks below.
.. _use_default_settings.yml:
Configuration
=============
.. sidebar:: ``use_default_settings: True``
- :ref:`settings.yml`
- :ref:`settings location`
- :ref:`settings use_default_settings`
- :origin:`/etc/searxng/settings.yml <utils/templates/etc/searxng/settings.yml>`
To create a initial ``/etc/searxng/settings.yml`` we recommend to start with a
copy of the file :origin:`utils/templates/etc/searxng/settings.yml`. This setup
:ref:`use default settings <settings use_default_settings>` from
:origin:`searx/settings.yml` and is shown in the tab *"Use default settings"*
below. This setup:
- enables :ref:`limiter <limiter>` to protect against bots
- enables :ref:`image proxy <image_proxy>` for better privacy
- enables :ref:`cache busting <static_use_hash>` to save bandwith
Modify the ``/etc/searxng/settings.yml`` to your needs:
.. tabs::
.. group-tab:: Use default settings
.. literalinclude:: ../../utils/templates/etc/searxng/settings.yml
:language: yaml
:end-before: # hostname_replace:
To see the entire file jump to :origin:`utils/templates/etc/searxng/settings.yml`
.. group-tab:: searx/settings.yml
.. literalinclude:: ../../searx/settings.yml
:language: yaml
:end-before: # hostname_replace:
To see the entire file jump to :origin:`searx/settings.yml`
For a *minimal setup* you need to set ``server:secret_key``.
.. kernel-include:: $DOCS_BUILD/includes/searxng.rst
:start-after: START searxng config
:end-before: END searxng config
Check
=====
To check your SearXNG setup, optional enable debugging and start the *webapp*.
SearXNG looks at the exported environment ``$SEARXNG_SETTINGS_PATH`` for a
configuration file.
.. kernel-include:: $DOCS_BUILD/includes/searxng.rst
:start-after: START check searxng installation
:end-before: END check searxng installation
If everything works fine, hit ``[CTRL-C]`` to stop the *webapp* and disable the
debug option in ``settings.yml``. You can now exit SearXNG user bash session (enter exit
command twice). At this point SearXNG is not demonized; uwsgi allows this.

Origin uWSGI
============
.. _Tyrant mode:
https://uwsgi-docs.readthedocs.io/en/latest/Emperor.html#tyrant-mode-secure-multi-user-hosting
How uWSGI is implemented by distributors varies. The uWSGI project itself
recommends two methods:
1. `systemd.unit`_ template file as described here `One service per app in systemd`_:
There is one `systemd unit template`_ on the system installed and one `uwsgi
ini file`_ per uWSGI-app placed at dedicated locations. Take archlinux and a
``searxng.ini`` as example::
systemd template unit: /usr/lib/systemd/system/uwsgi@.service
contains: [Service]
ExecStart=/usr/bin/uwsgi --ini /etc/uwsgi/%I.ini
SearXNG application: /etc/uwsgi/searxng.ini
links to: /etc/uwsgi/apps-available/searxng.ini
The SearXNG app (template ``/etc/uwsgi/%I.ini``) can be maintained as known
from common systemd units:
.. code:: sh
$ systemctl enable uwsgi@searxng
$ systemctl start uwsgi@searxng
$ systemctl restart uwsgi@searxng
$ systemctl stop uwsgi@searxng
2. The `uWSGI Emperor`_ which fits for maintaining a large range of uwsgi
apps and there is a `Tyrant mode`_ to secure multi-user hosting.
The Emperor mode is a special uWSGI instance that will monitor specific
events. The Emperor mode (the service) is started by a (common, not template)
systemd unit.
The Emperor service will scan specific directories for `uwsgi ini file`_\s
(also know as *vassals*). If a *vassal* is added, removed or the timestamp is
modified, a corresponding action takes place: a new uWSGI instance is started,
reload or stopped. Take Fedora and a ``searxng.ini`` as example::
to install & start SearXNG instance create --> /etc/uwsgi.d/searxng.ini
to reload the instance edit timestamp --> touch /etc/uwsgi.d/searxng.ini
to stop instance remove ini --> rm /etc/uwsgi.d/searxng.ini
Distributors
============
The `uWSGI Emperor`_ mode and `systemd unit template`_ is what the distributors
mostly offer their users, even if they differ in the way they implement both
modes and their defaults. Another point they might differ in is the packaging of
plugins (if so, compare :ref:`install packages`) and what the default python
interpreter is (python2 vs. python3).
While archlinux does not start a uWSGI service by default, Fedora (RHEL) starts
a Emperor in `Tyrant mode`_ by default (you should have read :ref:`uWSGI Tyrant
mode pitfalls`). Worth to know; debian (ubuntu) follow a complete different
approach, read see :ref:`Debian's uWSGI layout`.
.. _Debian's uWSGI layout:
Debian's uWSGI layout
---------------------
.. _uwsgi.README.Debian:
https://salsa.debian.org/uwsgi-team/uwsgi/-/raw/debian/latest/debian/uwsgi.README.Debian
Be aware, Debian's uWSGI layout is quite different from the standard uWSGI
configuration. Your are familiar with :ref:`Debian's Apache layout`? .. they do a
similar thing for the uWSGI infrastructure. The folders are::
/etc/uwsgi/apps-available/
/etc/uwsgi/apps-enabled/
The `uwsgi ini file`_ is enabled by a symbolic link::
ln -s /etc/uwsgi/apps-available/searxng.ini /etc/uwsgi/apps-enabled/
More details can be found in the uwsgi.README.Debian_
(``/usr/share/doc/uwsgi/README.Debian.gz``). Some commands you should know on
Debian:
.. code:: none
Commands recognized by init.d script
====================================
You can issue to init.d script following commands:
* start | starts daemon
* stop | stops daemon
* reload | sends to daemon SIGHUP signal
* force-reload | sends to daemon SIGTERM signal
* restart | issues 'stop', then 'start' commands
* status | shows status of daemon instance (running/not running)
'status' command must be issued with exactly one argument: '<confname>'.
Controlling specific instances of uWSGI
=======================================
You could control specific instance(s) by issuing:
SYSTEMCTL_SKIP_REDIRECT=1 service uwsgi <command> <confname> <confname>...
where:
* <command> is one of 'start', 'stop' etc.
* <confname> is the name of configuration file (without extension)
For example, this is how instance for /etc/uwsgi/apps-enabled/hello.xml is
started:
SYSTEMCTL_SKIP_REDIRECT=1 service uwsgi start hello

.. _uWSGI Tyrant mode pitfalls:
Pitfalls of the Tyrant mode
===========================
The implementation of the process owners and groups in the `Tyrant mode`_ is
somewhat unusual and requires special consideration. In `Tyrant mode`_ mode the
Emperor will run the vassal using the UID/GID of the vassal configuration file
(user and group of the app ``.ini`` file).
.. _#2099@uWSGI: https://github.com/unbit/uwsgi/issues/2099
.. _#752@uWSGI: https://github.com/unbit/uwsgi/pull/752
.. _#2425uWSGI: https://github.com/unbit/uwsgi/issues/2425
Without option ``emperor-tyrant-initgroups=true`` in ``/etc/uwsgi.ini`` the
process won't get the additional groups, but this option is not available in
2.0.x branch (see `#2099@uWSGI`_) the feature `#752@uWSGI`_ has been merged (on
Oct. 2014) to the master branch of uWSGI but had never been released; the last
major release is from Dec. 2013, since the there had been only bugfix releases
(see `#2425uWSGI`_). To shorten up:
**In Tyrant mode, there is no way to get additional groups, and the uWSGI
process misses additional permissions that may be needed.**
For example on Fedora (RHEL): If you try to install a redis DB with socket
communication and you want to connect to it from the SearXNG uWSGI, you will see a
*Permission denied* in the log of your instance::
ERROR:searx.redisdb: [searxng (993)] can't connect redis DB ...
ERROR:searx.redisdb: Error 13 connecting to unix socket: /usr/local/searxng-redis/run/redis.sock. Permission denied.
ERROR:searx.plugins.limiter: init limiter DB failed!!!
Even if your *searxng* user of the uWSGI process is added to additional groups
to give access to the socket from the redis DB::
$ groups searxng
searxng : searxng searxng-redis
To see the effective groups of the uwsgi process, you have to look at the status
of the process, by example::
$ ps -aef | grep '/usr/sbin/uwsgi --ini searxng.ini'
searxng 93 92 0 12:43 ? 00:00:00 /usr/sbin/uwsgi --ini searxng.ini
searxng 186 93 0 12:44 ? 00:00:01 /usr/sbin/uwsgi --ini searxng.ini
Here you can see that the additional "Groups" of PID 186 are unset (missing gid
of ``searxng-redis``)::
$ cat /proc/186/task/186/status
...
Uid: 993 993 993 993
Gid: 993 993 993 993
FDSize: 128
Groups:
...

settings.yml location
=====================
The initial ``settings.yml`` we be load from these locations:
1. the full path specified in the ``SEARXNG_SETTINGS_PATH`` environment variable.
2. ``/etc/searxng/settings.yml``
If these files don't exist (or are empty or can't be read), SearXNG uses the
:origin:`searx/settings.yml` file. Read :ref:`settings use_default_settings` to
see how you can simplify your *user defined* ``settings.yml``.
.. _settings use_default_settings:
use_default_settings
====================
.. sidebar:: ``use_default_settings: true``
- :ref:`settings location`
- :ref:`use_default_settings.yml`
- :origin:`/etc/searxng/settings.yml <utils/templates/etc/searxng/settings.yml>`
The user defined ``settings.yml`` is loaded from the :ref:`settings location`
and can relied on the default configuration :origin:`searx/settings.yml` using:
``use_default_settings: true``
``server:``
In the following example, the actual settings are the default settings defined
in :origin:`searx/settings.yml` with the exception of the ``secret_key`` and
the ``bind_address``:
.. code:: yaml
use_default_settings: true
server:
secret_key: "ultrasecretkey" # change this!
bind_address: "0.0.0.0"
``engines:``
With ``use_default_settings: true``, each settings can be override in a
similar way, the ``engines`` section is merged according to the engine
``name``. In this example, SearXNG will load all the default engines, will
enable the ``bing`` engine and define a :ref:`token <private engines>` for
the arch linux engine:
.. code:: yaml
use_default_settings: true
server:
secret_key: "ultrasecretkey" # change this!
engines:
- name: arch linux wiki
tokens: ['$ecretValue']
- name: bing
disabled: false
``engines:`` / ``remove:``
It is possible to remove some engines from the default settings. The following
example is similar to the above one, but SearXNG doesn't load the the google
engine:
.. code:: yaml
use_default_settings:
engines:
remove:
- google
server:
secret_key: "ultrasecretkey" # change this!
engines:
- name: arch linux wiki
tokens: ['$ecretValue']
``engines:`` / ``keep_only:``
As an alternative, it is possible to specify the engines to keep. In the
following example, SearXNG has only two engines:
.. code:: yaml
use_default_settings:
engines:
keep_only:
- google
- duckduckgo
server:
secret_key: "ultrasecretkey" # change this!
engines:
- name: google
tokens: ['$ecretValue']
- name: duckduckgo

``name`` :
Name that will be used across SearXNG to define this engine. In settings, on
the result page...
``engine`` :
Name of the python file used to handle requests and responses to and from this
search engine.
``shortcut`` :
Code used to execute bang requests (in this case using ``!bi``)
``base_url`` : optional
Part of the URL that should be stable across every request. Can be useful to
use multiple sites using only one engine, or updating the site URL without
touching at the code.
``send_accept_language_header`` :
Several engines that support languages (or regions) deal with the HTTP header
``Accept-Language`` to build a response that fits to the locale. When this
option is activated, the language (locale) that is selected by the user is used
to build and send a ``Accept-Language`` header in the request to the origin
search engine.
.. _engine categories:
``categories`` : optional
Specifies to which categories the engine should be added. Engines can be
assigned to multiple categories.
Categories can be shown as tabs (:ref:`settings categories_as_tabs`) in the
UI. A search in a tab (in the UI) will query all engines that are active in
this tab. In the preferences page (``/preferences``) -- under *engines* --
users can select what engine should be active when querying in this tab.
Alternatively, :ref:`\!bang <search-syntax>` can be used to search all engines
in a category, regardless of whether they are active or not, or whether they
are in a tab of the UI or not. For example, ``!dictionaries`` can be used to
query all search engines in that category (group).
``timeout`` : optional
Timeout of the search with the current search engine. Overwrites
``request_timeout`` from :ref:`settings outgoing`. **Be careful, it will
modify the global timeout of SearXNG.**
``api_key`` : optional
In a few cases, using an API needs the use of a secret key. How to obtain them
is described in the file.
``disabled`` : optional
To disable by default the engine, but not deleting it. It will allow the user
to manually activate it in the settings.
``inactive``: optional
Remove the engine from the settings (*disabled & removed*).
``language`` : optional
If you want to use another language for a specific engine, you can define it
by using the ISO code of language (and region), like ``fr``, ``en-US``,
``de-DE``.
``tokens`` : optional
A list of secret tokens to make this engine *private*, more details see
:ref:`private engines`.
``weight`` : default ``1``
Weighting of the results of this engine.
``display_error_messages`` : default ``true``
When an engine returns an error, the message is displayed on the user interface.
``network`` : optional
Use the network configuration from another engine.
In addition, there are two default networks:
- ``ipv4`` set ``local_addresses`` to ``0.0.0.0`` (use only IPv4 local addresses)
- ``ipv6`` set ``local_addresses`` to ``::`` (use only IPv6 local addresses)
``enable_http`` : optional
Enable HTTP for this engine (by default only HTTPS is enabled).
``retry_on_http_error`` : optional
Retry request on some HTTP status code.
Example:
* ``true`` : on HTTP status code between 400 and 599.
* ``403`` : on HTTP status code 403.
* ``[403, 429]``: on HTTP status code 403 and 429.
``proxies`` :
Overwrites proxy settings from :ref:`settings outgoing`.
``using_tor_proxy`` :
Using tor proxy (``true``) or not (``false``) for this engine. The default is
taken from ``using_tor_proxy`` of the :ref:`settings outgoing`.
.. _Pool limit configuration: https://www.python-httpx.org/advanced/#pool-limit-configuration
``max_keepalive_connection#s`` :
`Pool limit configuration`_, overwrites value ``pool_maxsize`` from
:ref:`settings outgoing` for this engine.
``max_connections`` :
`Pool limit configuration`_, overwrites value ``pool_connections`` from
:ref:`settings outgoing` for this engine.
``keepalive_expiry`` :
`Pool limit configuration`_, overwrites value ``keepalive_expiry`` from
:ref:`settings outgoing` for this engine.
.. _private engines:
Private Engines (``tokens``)
============================
Administrators might find themselves wanting to limit access to some of the
enabled engines on their instances. It might be because they do not want to
expose some private information through :ref:`offline engines`. Or they would
rather share engines only with their trusted friends or colleagues.
.. sidebar:: info
Initial sponsored by `Search and Discovery Fund
<https://nlnet.nl/discovery>`_ of `NLnet Foundation <https://nlnet.nl/>`_.
To solve this issue the concept of *private engines* exists.
A new option was added to engines named `tokens`. It expects a list of strings.
If the user making a request presents one of the tokens of an engine, they can
access information about the engine and make search requests.
Example configuration to restrict access to the Arch Linux Wiki engine:
.. code:: yaml
- name: arch linux wiki
engine: archlinux
shortcut: al
tokens: [ 'my-secret-token' ]
Unless a user has configured the right token, the engine is going to be hidden
from him/her. It is not going to be included in the list of engines on the
Preferences page and in the output of `/config` REST API call.
Tokens can be added to one's configuration on the Preferences page under "Engine
tokens". The input expects a comma separated list of strings.
The distribution of the tokens from the administrator to the users is not carved
in stone. As providing access to such engines implies that the admin knows and
trusts the user, we do not see necessary to come up with a strict process.
Instead, we would like to add guidelines to the documentation of the feature.
Example: Multilingual Search
============================
SearXNG does not support true multilingual search. You have to use the language
prefix in your search query when searching in a different language.
But there is a workaround: By adding a new search engine with a different
language, SearXNG will search in your default and other language.
Example configuration in settings.yml for a German and English speaker:
.. code-block:: yaml
search:
default_lang : "de"
...
engines:
- name : google english
engine : google
language : en
...
When searching, the default google engine will return German results and
"google english" will return English results.

``request_timeout`` :
Global timeout of the requests made to others engines in seconds. A bigger
timeout will allow to wait for answers from slow engines, but in consequence
will slow SearXNG reactivity (the result page may take the time specified in the
timeout to load). Can be override by ``timeout`` in the :ref:`settings engine`.
``useragent_suffix`` :
Suffix to the user-agent SearXNG uses to send requests to others engines. If an
engine wish to block you, a contact info here may be useful to avoid that.
.. _Pool limit configuration: https://www.python-httpx.org/advanced/#pool-limit-configuration
``pool_maxsize``:
Number of allowable keep-alive connections, or ``null`` to always allow. The
default is 10. See ``max_keepalive_connections`` `Pool limit configuration`_.
``pool_connections`` :
Maximum number of allowable connections, or ``null`` # for no limits. The
default is 100. See ``max_connections`` `Pool limit configuration`_.

requests to the engines are distributed in a round-robin fashion.
``source_ips`` :
If you use multiple network interfaces, define from which IP the requests must
be made. Example:
* ``0.0.0.0`` any local IPv4 address.

.. _Redis.from_url(url): https://redis-py.readthedocs.io/en/stable/connections.html#redis.client.Redis.from_url
A redis DB can be connected by an URL, in :py:obj:`searx.redisdb` you
will find a description to test your redis connection in SerXNG. When using
sockets, don't forget to check the access rights on the socket::
ls -la /usr/local/searxng-redis/run/redis.sock
srwxrwx--- 1 searxng-redis searxng-redis ... /usr/local/searxng-redis/run/redis.sock
In this example read/write access is given to the *searxng-redis* group. To get
access rights to redis instance (the socket), your SearXNG (or even your
developer) account needs to be added to the *searxng-redis* group.
``url`` : ``$SEARXNG_REDIS_URL``
URL to connect redis database, see `Redis.from_url(url)`_ & :ref:`redis db`::
redis://[[username]:[password]]@localhost:6379/0

Redis Developer Notes
=====================
To set up a local redis instance, first set the socket path of the Redis DB
in your YAML setting:
.. code:: yaml
redis:
url: unix:///usr/local/searxng-redis/run/redis.sock?db=0
Then use the following commands to install the redis instance (:ref:`manage
redis.help`):
.. code:: sh
$ ./manage redis.build
$ sudo -H ./manage redis.install
$ sudo -H ./manage redis.addgrp "${USER}"
# don't forget to logout & login to get member of group

=======================
.. sidebar:: info
- :pull:`1332`
- :pull:`456`
- :pull:`A comment about rolling release <446#issuecomment-954730358>`
SearXNG is a *rolling release*; each commit to the master branch is a release.
SearXNG is growing rapidly, the services and opportunities are change every now
and then, to name just a few:
- Bot protection has been switched from filtron to SearXNG's :ref:`limiter
<limiter>`, this requires a :ref:`Redis <settings redis>` database.
- The image proxy morty is no longer needed, it has been replaced by the
:ref:`image proxy <image_proxy>` from SearXNG.
- To save bandwith :ref:`cache busting <static_use_hash>` has been implemented.
To get in use, the ``static-expires`` needs to be set in the :ref:`uwsgi
setup`.
To stay tuned and get in use of the new features, instance maintainers have to
update the SearXNG code regularly (see :ref:`update searxng`). As the above
examples show, this is not always enough, sometimes services have to be set up
or reconfigured and sometimes services that are no longer needed should be
uninstalled.
.. hint::
First of all: SearXNG is installed by the script :ref:`searxng.sh`. If you
have old filtron, morty or searx setup you should consider complete
uninstall/reinstall.
Here you will find a list of changes that affect the infrastructure. Please
check to what extent it is necessary to update your installations:
:pull:`1595`: ``[fix] uWSGI: increase buffer-size``
Re-install uWSGI (:ref:`searxng.sh`) or fix your uWSGI ``searxng.ini``
file manually.
remove obsolete services
------------------------
If your searx instance was installed *"Step by step"* or by the *"Installation
scripts"*, you need to undo the installation procedure completely. If you have
morty & filtron installed, it is recommended to uninstall these services also.
In case of scripts, to uninstall use the scripts from the origin you installed
searx from or try::
$ sudo -H ./utils/filtron.sh remove all
$ sudo -H ./utils/morty.sh remove all
$ sudo -H ./utils/searx.sh remove all
.. hint::
If you are migrate from searx take into account that the ``.config.sh`` is no
longer used.
If you upgrade from searx or from before :pull:`1332` has been merged and you
have filtron and/or morty installed, don't forget to remove HTTP sites.
Apache::
$ sudo -H ./utils/filtron.sh apache remove
$ sudo -H ./utils/morty.sh apache remove
nginx::
$ sudo -H ./utils/filtron.sh nginx remove
$ sudo -H ./utils/morty.sh nginx remove
Check after Installation
------------------------
Once you have done your installation, you can run a SearXNG *check* procedure,
to see if there are some left overs. In this example there exists a *old*
``/etc/searx/settings.yml``::
$ sudo -H ./utils/searxng.sh instance check
SearXNG checks

Prime directives: Privacy, Hackability
======================================
SearXNG has two prime directives, **privacy-by-design and hackability** . The
hackability comes in three levels:
- support of search engines
- plugins to alter search behaviour
- hacking SearXNG itself
Note the lack of "world domination" among the directives. SearXNG has no
intention of wide mass-adoption, rounded corners, etc. The prime directive
"privacy" deserves a separate chapter, as it's quite uncommon unfortunately.
Privacy-by-design
-----------------
SearXNG was born out of the need for a **privacy-respecting** search tool which
can be extended easily to maximize both, its search and its privacy protecting
capabilities.
A few widely used features work differently or turned off by default or not
implemented at all **as a consequence of privacy-by-design**.
If a feature reduces the privacy preserving aspects of searx, it should be
switched off by default or should not implemented at all. There are plenty of
search engines already providing such features. If a feature reduces the
protection of searx, users must be informed about the effect of choosing to
enable it. Features that protect privacy but differ from the expectations of
the user should also be explained.
Also, if you think that something works weird with searx, it's might be because
of the tool you use is designed in a way to interfere with the privacy respect.
Submitting a bugreport to the vendor of the tool that misbehaves might be a good
feedback to reconsider the disrespect to its customers (e.g. ``GET`` vs ``POST``
requests in various browsers).
Remember the other prime directive of SearXNG is to be hackable, so if the above
privacy concerns do not fancy you, simply fork it.
*Happy hacking.*

Documentation
=============
.. _Sphinx: https://www.sphinx-doc.org
.. _reST: https://www.sphinx-doc.org/en/master/usage/restructuredtext/basics.html
.. sidebar:: The reST sources
has been moved from ``gh-branch`` into ``master`` (:origin:`docs`).
The documentation is built using Sphinx_. So in order to be able to generate
the required files, you have to install it on your system. Much easier, use
our :ref:`makefile`.
Here is an example which makes a complete rebuild:
.. code:: sh
$ make docs.clean docs.html
...
The HTML pages are in dist/docs.
.. _make docs.live:
live build
----------
.. _sphinx-autobuild:
https://github.com/executablebooks/sphinx-autobuild/blob/master/README.md
.. sidebar:: docs.clean
It is recommended to assert a complete rebuild before deploying (use
``docs.clean``).
Live build is like WYSIWYG. If you want to edit the documentation, its
recommended to use. The Makefile target ``docs.live`` builds the docs, opens
URL in your favorite browser and rebuilds every time a reST file has been
changed (:ref:`make docs.clean`).
.. code:: sh
$ make docs.live
...
The HTML pages are in dist/docs.
... Serving on http://0.0.0.0:8000
... Start watching changes
Live builds are implemented by sphinx-autobuild_. Use environment
``$(SPHINXOPTS)`` to pass arguments to the sphinx-autobuild_ command. Except
option ``--host`` (which is always set to ``0.0.0.0``) you can pass any
argument. E.g to find and use a free port, use:
.. code:: sh
$ SPHINXOPTS="--port 0" make docs.live
...
... Serving on http://0.0.0.0:50593
...
.. _deploy on github.io:
deploy on github.io
-------------------
To deploy documentation at :docs:`github.io <.>` use Makefile target :ref:`make
docs.gh-pages`, which builds the documentation and runs all the needed git add,
commit and push:
.. code:: sh
$ make docs.clean docs.gh-pages
.. attention::
If you are working in your own brand, don't forgett to adjust your
:ref:`settings brand`.
