"""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::

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*
