"""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.

|
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.
