"""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 engine>`:
|
|
|
|
.. code:: yaml
|
|
|
|
- name: qwant
|
|
qwant_categ: web-lite # alternatively use 'web'
|
|
...
|
|
- name: qwant news
|
|
qwant_categ: news
|
|
...
|
|
- name: qwant images
|

qwant_categ: images
