Plugins can extend or replace functionality of various components of SearXNG.
|
|
|
|
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.
|
|
|
|
- pre search: :py:obj:`Plugin.pre_search`
|
|
- post search: :py:obj:`Plugin.post_search`
|
|
- on each result item: :py:obj:`Plugin.on_result`
|
|
|
|
Below you will find some examples, for more coding examples have a look at the
|
|
built-in plugins :origin:`searx/plugins/` or `Only show green hosted results`_.

Add Answer example
|
|
==================
|
|
|
|
Here is an example of a very simple plugin that adds a "Hello World" into the
|
|
answer area:
|
|
|
|
.. code:: python
|
|
|
|
from flask_babel import gettext as _
|
|
from searx.plugins import Plugin
|
|
from searx.result_types import Answer
|
|
|
|
class MyPlugin(Plugin):
|
|
|
|
id = "hello world"
|
|
|
|
def __init__(self, plg_cfg):
|
|
super().__init__(plg_cfg)
|
|
self.info = PluginInfo(id=self.id, name=_("Hello"), description=_("demo plugin"))
|
|
|
|
def post_search(self, request, search):
|
|
return [ Answer(answer="Hello World") ]

Filter URLs example
|
|
===================
|
|
|
|
.. sidebar:: Further reading ..
|
|
|
|
- :py:obj:`Result.filter_urls(..) <searx.result_types._base.Result.filter_urls>`
|
|
|
|
The :py:obj:`Result.filter_urls(..) <searx.result_types._base.Result.filter_urls>`
|
|
can be used to filter and/or modify URL fields. In the following example, the
|
|
filter function ``my_url_filter``:
|
|
|
|
.. code:: python
|
|
|
|
def my_url_filter(result, field_name, url_src) -> bool | str:
|
|
if "google" in url_src:
|
|
return False # remove URL field from result
|
|
if "facebook" in url_src:
|
|
new_url = url_src.replace("facebook", "fb-dummy")
|
|
return new_url # return modified URL
|
|
return True # leave URL in field unchanged
|
|
|
|
is applied to all URL fields in the :py:obj:`Plugin.on_result` hook:
|
|
|
|
.. code:: python
|
|
|
|
class MyUrlFilter(Plugin):
|
|
...
|
|
def on_result(self, request, search, result) -> bool:
|
|
result.filter_urls(my_url_filter)
|
|
return True
|
|
|
|
|
|
