"""Presearch (general, images, videos, news)
|

|

.. hint::
|
||||
|
||||
The results in the video category are most often links to pages that contain
|
||||
a video, for instance many links from preasearch's video category link
|
||||
content from facebook (aka Meta) or Twitter (aka X). Since these are not
|
||||
real links to video streams SearXNG can't use the video template for this and
|
||||
if SearXNG can't use this template, then the user doesn't want to see these
|
||||
hits in the videos category.
|
||||
|
||||
TL;DR; by default presearch's video category is placed into categories::
|
||||
|
||||
categories: [general, web]
