"""BT4G_ (bt4g.com) is not a tracker and doesn't store any content and only
collects torrent metadata (such as file names and file sizes) and a magnet link
(torrent identifier).
This engine does not parse the HTML page because there is an API in XML (RSS).
The RSS feed provides fewer data like amount of seeders/leechers and the files
in the torrent file. It's a tradeoff for a "stable" engine as the XML from RSS
content will change way less than the HTML page.
.. _BT4G: https://bt4g.com/
Configuration
=============
The engine has the following additional settings:
- :py:obj:`bt4g_order_by`
- :py:obj:`bt4g_category`
With this options a SearXNG maintainer is able to configure **additional**
engines for specific torrent searches. For example a engine to search only for
Movies and sort the result list by the count of seeders.
.. code:: yaml
- name: bt4g.movie
engine: bt4g
shortcut: bt4gv
categories: video
bt4g_order_by: seeders
bt4g_category: 'movie'
