"""The MediaWiki engine is a *generic* engine to **query** Wikimedia wikis by
|
||||
the `MediaWiki Action API`_. For a `query action`_ all Wikimedia wikis have
|
||||
endpoints that follow this pattern::
|
||||
|
||||
from string import Formatter
|
||||
https://{base_url}/w/api.php?action=query&list=search&format=json
|
||||
|
||||
.. note::
|
||||
|
||||
In its actual state, this engine is implemented to parse JSON result
|
||||
(`format=json`_) from a search query (`list=search`_). If you need other
|
||||
``action`` and ``list`` types ask SearXNG developers to extend the
|
||||
implementation according to your needs.
