The use of img_src AND thumbnail in the default results makes no sense (only a thumbnail is needed). In the current state this is rather confusing, because img_src is displayed like a thumbnail (small) and thumbnail is displayed like an image (large).

"""This is the implementation of the Google News engine.
|
|
|
|
Google News has a different region handling compared to Google WEB.
|
|
|
|
- the ``ceid`` argument has to be set (:py:obj:`ceid_list`)
|
|
- the hl_ argument has to be set correctly (and different to Google WEB)
|
|
- the gl_ argument is mandatory
|
|
|
|
If one of this argument is not set correctly, the request is redirected to
|
|
CONSENT dialog::
|
|
|
|
https://consent.google.com/m?continue=
|
|
|
|
The google news API ignores some parameters from the common :ref:`google API`:
|
|
|
|
- num_ : the number of search results is ignored / there is no paging all
|
|
results for a query term are in the first response.
|
|
- save_ : is ignored / Google-News results are always *SafeSearch*
