Plugins can extend or replace functionality of various components of searx.

Example plugin

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):
    return True

External plugins

External plugins are standard python modules implementing all the requirements of the standard plugins. Plugins can be enabled by adding them to settings.yml’s plugins section. Example external plugin can be found here.

Register your plugin

To enable your plugin register your plugin in searx > plugin > And at the bottom of the file add your plugin like. plugins.register(name_of_python_file)

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.
