[doc] rearranges Settings & Engines docs for better readability
We have built up detailed documentation of the *settings* and the *engines* over the past few years. However, this documentation was still spread over various chapters and was difficult to navigate in its entirety. This patch rearranges the Settings & Engines documentation for better readability. To review new ordered docs:: make docs.clean docs.live Signed-off-by: Markus Heiser <markus.heiser@darmarit.de>

Command Line Engines
|

====================

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

|

|

============================
|
||||
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.
|
||||
|
||||
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.

Recoll_ is a desktop full-text search tool based on Xapian. By itself Recoll_
|
||||
does not offer WEB or API access, this can be achieved using recoll-webui_
|
||||
|
||||
|
||||
Configuration
|
||||
=============
|
||||
|
||||
You must configure the following settings:
|
||||
|
||||
``base_url``:
|
||||
Location where recoll-webui can be reached.
|
||||
|
||||
``mount_prefix``:
|
||||
Location where the file hierarchy is mounted on your *local* filesystem.
|
||||
|
||||
``dl_prefix``:
|
||||
Location where the file hierarchy as indexed by recoll can be reached.
|
||||
|
||||
``search_dir``:
|
||||
Part of the indexed file hierarchy to be search, if empty the full domain is
|
||||
searched.
|
||||
|
||||
|
||||
Example
|
||||
=======
|
||||
|
||||
Scenario:
|
||||
|
||||
#. Recoll indexes a local filesystem mounted in ``/export/documents/reference``,
|
||||
#. the Recoll search interface can be reached at https://recoll.example.org/ and
|
||||
#. the contents of this filesystem can be reached though https://download.example.org/reference
|
||||
|
||||
.. code:: yaml

||||
|
||||
base_url: https://recoll.example.org/
|

|

|

Administrators might find themselves wanting to integrate locally running search
|
||||
engines. The following ones are supported for now:
|
||||
|
||||
* `Elasticsearch`_
|
||||
* `Meilisearch`_
|
||||
* `Solr`_
|
||||
|
||||
Each search engine is powerful, capable of full-text search. All of the engines
|
||||
above are added to ``settings.yml`` just commented out, as you have to
|
||||
``base_url`` for all them.
|
||||
|
||||
Please note that if you are not using HTTPS to access these engines, you have to enable
|
||||
HTTP requests by setting ``enable_http`` to ``True``.
|
||||
|
||||
Furthermore, if you do not want to expose these engines on a public instance, you
|
||||
can still add them and limit the access by setting ``tokens`` as described in
|
||||
section :ref:`private engines`.
|
||||
|
||||

MeiliSearch

|
||||
|
||||
MeiliSearch_ is aimed at individuals and small companies. It is designed for
|
||||
small-scale (less than 10 million documents) data collections. E.g. it is great
|
||||
for storing web pages you have visited and searching in the contents later.
|
||||
|
||||
The engine supports faceted search, so you can search in a subset of documents
|
||||
of the collection. Furthermore, you can search in MeiliSearch_ instances that
|
||||
require authentication by setting ``auth_token``.
|
||||
|
||||
Here is a simple example to query a Meilisearch instance:
|
||||
|
||||
.. code:: yaml
|
||||
|
||||
- name: meilisearch
|
||||
engine: meilisearch
|
||||
shortcut: mes
|
||||
base_url: http://localhost:7700
|
||||
index: my-index
|
||||
enable_http: true
|
||||
|
||||

|
||||

||||
Elasticsearch
|
||||
=============
|
||||
|
||||

|

|
||||
- :origin:`elasticsearch.py <searx/engines/elasticsearch.py>`
|
||||

||||

||||

- `Install Elasticsearch
|

<https://www.elastic.co/guide/en/elasticsearch/reference/current/install-elasticsearch.html>`_
|
||||
|
||||
Elasticsearch_ supports numerous ways to query the data it is storing. At the
|
||||
moment the engine supports the most popular search methods (``query_type``):
|
||||
|
||||
- ``match``,
|
||||
- ``simple_query_string``,
|
||||
- ``term`` and
|
||||
- ``terms``.
|
||||
|
||||
If none of the methods fit your use case, you can select ``custom`` query type
|
||||
and provide the JSON payload to submit to Elasticsearch in
|
||||
``custom_query_json``.
|
||||
|
||||
The following is an example configuration for an Elasticsearch_ instance with
|
||||
authentication configured to read from ``my-index`` index.
|
||||
|
||||
.. code:: yaml
|
||||
|
||||
- name: elasticsearch
|
||||
shortcut: es
|
||||
engine: elasticsearch
|
||||
base_url: http://localhost:9200
|
||||
username: elastic
|
||||
password: changeme
|
||||
index: my-index
|
||||
query_type: match
|
||||
# custom_query_json: '{ ... }'
|
||||
enable_http: true
|
||||
|
||||

|
||||
|
||||
Solr_ is a popular search engine based on Lucene, just like Elasticsearch_. But
|
||||
instead of searching in indices, you can search in collections.
|
||||
|
||||
This is an example configuration for searching in the collection
|
||||
``my-collection`` and get the results in ascending order.
|
||||
|
||||
.. code:: yaml
|
||||
|
||||
- name: solr

.. _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
|
||||
rediss://[[username]:[password]]@localhost:6379/0
|
||||
unix://[[username]:[password]]@/path/to/socket.sock?db=0
|
||||
|
||||
.. admonition:: Tip for developers
|
||||
|
||||
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 ::
|
||||
|
||||
$ ./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

#
|
||||
|
||||
``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``:

|
||||
default is 10. See ``max_keepalive_connections`` `Pool limit configuration`_.
|
||||
|
||||

||||
|
||||
``keepalive_expiry`` :
|
||||

|
||||
|
||||
``proxies`` :
|
||||
Define one or more proxies you wish to use, see `httpx proxies`_.
|
||||
If there are more than one proxy for one protocol (http, https),
|
||||
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:
|
||||
|
||||

|
||||
* ``::`` any local IPv6 address.
|
||||
* ``192.168.0.1``
|
||||
* ``[ 192.168.0.1, 192.168.0.2 ]`` these two specific IP addresses
|
||||
* ``fe80::60a2:1691:e5a2:ee1f``
|
||||
* ``fe80::60a2:1691:e5a2:ee1f/126`` all IP addresses in this network.

|
||||
|
||||
``retries`` :

|
||||
different proxy and source ip.
|
||||
|
||||
``enable_http2`` :
|
||||
Enable by default. Set to ``false`` to disable HTTP/2.
|
||||
|
||||
.. _httpx verification defaults: https://www.python-httpx.org/advanced/#changing-the-verification-defaults

||||
|
||||
``verify``: : ``$SSL_CERT_FILE``, ``$SSL_CERT_DIR``
|
||||
Allow to specify a path to certificate.
|
||||
see `httpx verification defaults`_.
|
||||
|
||||
In addition to ``verify``, SearXNG supports the ``$SSL_CERT_FILE`` (for a file) and
|
||||
``$SSL_CERT_DIR`` (for a directory) OpenSSL variables.
|
||||
see `httpx ssl configuration`_.
|
||||

|
||||
|
||||

user disables all engines in a category).
|
||||
|
||||
On the preferences page (``/preferences``) -- under *engines* -- there is an
|

|
||||
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 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.

|
||||
Overwrites proxy settings from :ref:`settings outgoing`.
|
||||
|
||||
``using_tor_proxy`` :

||||
|
||||
``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.
|
||||
|
||||

A few more options are possible, but they are pretty specific to some
|
||||
engines, and so won't be described here.
|
||||
|
||||
|
||||
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.
|
||||
|
||||
|
||||
.. _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-block:: 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-block:: yaml
|
||||
|
||||
use_default_settings: true
|
||||
server:
|
||||
secret_key: "ultrasecretkey" # change this!
|
||||
engines:
|
||||
- name: arch linux wiki
|
||||
tokens: ['$ecretValue']
|
||||
- name: bing
|
||||
disabled: false
|
||||
|
||||
|
||||
``engines:`` / ``remove:``
|
||||
It is possible to remove some engines from the default settings. The following
|
||||
example is similar to the above one, but SearXNG doesn't load the the google
|
||||
engine:
|
||||
|
||||
.. code-block:: yaml
|
||||
|
||||
use_default_settings:
|
||||
engines:
|
||||
remove:
|
||||
- google
|
||||
server:
|
||||
secret_key: "ultrasecretkey" # change this!
|
||||
engines:
|
||||
- name: arch linux wiki
|
||||
tokens: ['$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-block:: yaml
|
||||
|
||||
use_default_settings:
|
||||
engines:
|
||||
keep_only:
|
||||
- google
|
||||
- duckduckgo
|
||||
server:
|
||||
secret_key: "ultrasecretkey" # change this!
|
||||
engines:
|
||||
- name: google
|
||||
tokens: ['$ecretValue']
|
||||
- name: duckduckgo
|
||||

|

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``

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

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:

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

.. _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
|
||||
rediss://[[username]:[password]]@localhost:6379/0
|
||||
unix://[[username]:[password]]@/path/to/socket.sock?db=0
|
||||
|
||||
.. admonition:: Tip for developers
|
||||
|
||||
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 ::
|
||||
|
||||
$ ./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

Redis is an open source (BSD licensed), in-memory data structure (key value

based) store. Before configuring the ``redis_server`` engine, you must install

the dependency redis_.
|

Select a database to search in and set its index in the option ``db``. You can
|
||||
either look for exact matches or use partial keywords to find what you are
|

looking for by configuring ``exact_match_only``. You find an example
|

configuration below:

MongoDB_ is a document based database program that handles JSON like data.
|

Before configuring the ``mongodb`` engine, you must install the dependency

redis_.

In order to query MongoDB_, you have to select a ``database`` and a

``collection``. Furthermore, you have to select a ``key`` that is going to be

searched. MongoDB_ also supports the option ``exact_match_only``, so configure

Administrators might find themselves wanting to integrate locally running search
|
||||
engines. The following ones are supported for now:
|
||||
|
||||
* `Elasticsearch`_
|
||||
* `Meilisearch`_
|
||||
* `Solr`_
|
||||
|
||||
Each search engine is powerful, capable of full-text search. All of the engines
|
||||
above are added to ``settings.yml`` just commented out, as you have to
|
||||
``base_url`` for all them.
|
||||
|
||||
Please note that if you are not using HTTPS to access these engines, you have to
|
||||
enable HTTP requests by setting ``enable_http`` to ``True``.
|
||||
|
||||
Furthermore, if you do not want to expose these engines on a public instance,
|
||||
you can still add them and limit the access by setting ``tokens`` as described
|
||||
in section :ref:`private engines`.

SQLite is a small, fast and reliable SQL database engine. It does not require

any extra dependency. To demonstrate the power of database engines, here is a

|
||||
|

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