"""Qwant (Web, News, Images, Videos)
|

|

This engine uses the Qwant API (https://api.qwant.com/v3). The API is
|
||||
undocumented but can be reverse engineered by reading the network log of
|
||||
https://www.qwant.com/ queries.
|
||||
|
||||
This implementation is used by different qwant engines in the settings.yml::
