Plugins can extend or replace functionality of various components of searx.
|
|
|
|
Example plugin
|
|
==============
|
|
|
|
.. code:: python
|
|
|
|
name = 'Example plugin'
|
|
description = 'This plugin extends the suggestions with the word "example"'
|
|
default_on = False # disabled by default
|
|
|
|
js_dependencies = tuple() # optional, list of static js files
|
|
css_dependencies = tuple() # optional, list of static css files
|
|
|
|
|
|
# attach callback to the post search hook
|
|
# request: flask request object
|
|
# ctx: the whole local context of the post search hook
|
|
def post_search(request, search):
|
|
search.result_container.suggestions.add('example')
|
|
return True
|
|
|
|
External plugins
|
|
================
|
|
|
|
SearXNG supports *external plugins* / there is no need to install one, SearXNG
|
|
runs out of the box. But to demonstrate; in the example below we install the
|
|
SearXNG plugins from *The Green Web Foundation* `[ref]
|
|
<https://www.thegreenwebfoundation.org/news/searching-the-green-web-with-searx/>`__:
|
|
|
|
.. code:: bash
|
|
|
|
$ sudo utils/searxng.sh instance cmd bash
|
|
(searxng-pyenv)$ pip install git+https://github.com/return42/tgwf-searx-plugins
|
|
|
|
In the :ref:`settings.yml` activate the ``plugins:`` section and add module
|
|
``only_show_green_results`` from ``tgwf-searx-plugins``.
|
|
|
|
.. code:: yaml
|
|
|
|
plugins:
|
|
...
|
|
- only_show_green_results
|
|
...
|
|
|
|
|
|
Plugin entry points
|
|
===================
|
|
|
|
Entry points (hooks) define when a plugin runs. Right now only three hooks are
|
|
implemented. So feel free to implement a hook if it fits the behaviour of your
|
|
plugin. A plugin doesn't need to implement all the hooks.
|
|
|
|
|
|
.. py:function:: pre_search(request, search) -> bool
|
|
|
|
Runs BEFORE the search request.
|
|
|
|
`search.result_container` can be changed.
|
|
|
|
Return a boolean:
|
|
|
|
* True to continue the search
|
|
* False to stop the search
|
|
|
|
:param flask.request request:
|
|
:param searx.search.SearchWithPlugins search:
|
|
:return: False to stop the search
|
|
:rtype: bool
|
|
|
|
|
|
.. py:function:: post_search(request, search) -> None
|
|
|
|
Runs AFTER the search request.
|
|
|
|
:param flask.request request: Flask request.
|
|
:param searx.search.SearchWithPlugins search: Context.
|
|
|
|
|
|
.. py:function:: on_result(request, search, result) -> bool
|
|
|
|
Runs for each result of each engine.
|
|
|
|
`result` can be changed.
|
|
|
|
If `result["url"]` is defined, then `result["parsed_url"] = urlparse(result['url'])`
|
|
|
|
.. warning::
|
|
`result["url"]` can be changed, but `result["parsed_url"]` must be updated too.
|
|
|
|
Return a boolean:
|
|
|
|
* True to keep the result
|
|
* False to remove the result
|
|
|
|
:param flask.request request:
|
|
:param searx.search.SearchWithPlugins search:
|
|
:param typing.Dict result: Result, see - :ref:`engine results`
|
|
:return: True to keep the result
|

:rtype: bool
