"""This engine uses the Qwant API (https://api.qwant.com/v3) to implement Qwant
-Web, -News, -Images and -Videos. The API is undocumented but can be reverse
engineered by reading the network log of https://www.qwant.com/ queries.
For Qwant's *web-search* two alternatives are implemented:
- ``web``: uses the :py:obj:`api_url` which returns a JSON structure
- ``web-lite``: uses the :py:obj:`web_lite_url` which returns a HTML page
Configuration
=============
The engine has the following additional settings:
- :py:obj:`qwant_categ`
This implementation is used by different qwant engines in the :ref:`settings.yml
<settings engines>`:
.. code:: yaml
- name: qwant
qwant_categ: web-lite # alternatively use 'web'
...
- name: qwant news
qwant_categ: news
...
- name: qwant images
qwant_categ: images
...
- name: qwant videos
qwant_categ: videos
...
