2499899554 [mod] Google: reversed engineered & upgrade to data_type: traits_v1
Partial reverse engineering of the Google engines including a improved language
and region handling based on the engine.traits_v1 data.

When ever possible the implementations of the Google engines try to make use of
the async REST APIs.  The get_lang_info() has been generalized to a
get_google_info() function / especially the region handling has been improved by
adding the cr parameter.

searx/data/engine_traits.json
  Add data type "traits_v1" generated by the fetch_traits() functions from:

  - Google (WEB),
  - Google images,
  - Google news,
  - Google scholar and
  - Google videos

  and remove data from obsolete data type "supported_languages".

  A traits.custom type that maps region codes to *supported_domains* is fetched
  from https://www.google.com/supported_domains

searx/autocomplete.py:
  Reversed engineered autocomplete from Google WEB.  Supports Google's languages and
  subdomains.  The old API suggestqueries.google.com/complete has been replaced
  by the async REST API: https://{subdomain}/complete/search?{args}

searx/engines/google.py
  Reverse engineering and extensive testing ..
  - fetch_traits():  Fetch languages & regions from Google properties.
  - always use the async REST API (formally known as 'use_mobile_ui')
  - use *supported_domains* from traits
  - improved the result list by fetching './/div[@data-content-feature]'
    and parsing the type of the various *content features* --> thumbnails are
    added

searx/engines/google_images.py
  Reverse engineering and extensive testing ..
  - fetch_traits():  Fetch languages & regions from Google properties.
  - use *supported_domains* from traits
  - if exists, freshness_date is added to the result
  - issue 1864: result list has been improved a lot (due to the new cr parameter)

searx/engines/google_news.py
  Reverse engineering and extensive testing ..
  - fetch_traits():  Fetch languages & regions from Google properties.
    *supported_domains* is not needed but a ceid list has been added.
  - different region handling compared to Google WEB
  - fixed for various languages & regions (due to the new ceid parameter) /
    avoid CONSENT page
  - Google News do no longer support time range
  - result list has been fixed: XPath of pub_date and pub_origin

searx/engines/google_videos.py
  - fetch_traits():  Fetch languages & regions from Google properties.
  - use *supported_domains* from traits
  - add paging support
  - implement a async request ('asearch': 'arc' & 'async':
    'use_ac:true,_fmt:html')
  - simplified code (thanks to '_fmt:html' request)
  - issue 1359: fixed xpath of video length data

searx/engines/google_scholar.py
  - fetch_traits():  Fetch languages & regions from Google properties.
  - use *supported_domains* from traits
  - request(): include patents & citations
  - response(): fixed CAPTCHA detection (Scholar has its own CATCHA manager)
  - hardening XPath to iterate over results
  - fixed XPath of pub_type (has been change from gs_ct1 to gs_cgt2 class)
  - issue 1769 fixed: new request implementation is no longer incompatible

94b3656b4a [fix] google engine: results XPath
Seems google rolls out changes first on the `google.com` domain and later on the
"language" domains.  By example: yesterday [1] `google.com` did not work but
`google.de` and `google.fr` did work, today they do not work any longer and this
fix is needed on all domains.

5fb2071cb2 [fix] google & youtube - set EU consent cookie
This change the previous bypass method for Google consent using
``ucbcb=1`` (6face215b8) to accept the consent using ``CONSENT=YES+``.

The youtube_noapi and google have a similar API, at least for the consent[1].

Get CONSENT cookie from google reguest::

    curl -i "https://www.google.com/search?q=time&tbm=isch" \
         -A "Mozilla/5.0 (X11; Linux i686; rv:102.0) Gecko/20100101 Firefox/102.0" \
         | grep -i consent
    ...
    location: https://consent.google.com/m?continue=https://www.google.com/search?q%3Dtime%26tbm%3Disch&gl=DE&m=0&pc=irp&uxe=eomtm&hl=en-US&src=1
    set-cookie: CONSENT=PENDING+936; expires=Wed, 24-Jul-2024 11:26:20 GMT; path=/; domain=.google.com; Secure
    ...

PENDING & YES [2]:

  Google change the way for consent about YouTube cookies agreement in EU
  countries. Instead of showing a popup in the website, YouTube redirects the
  user to a new webpage at consent.youtube.com domain ...  Fix for this is to
  put a cookie CONSENT with YES+ value for every YouTube request

1c67b6aece [enh] google engine: supports "default language"
Same behaviour behaviour than Whoogle [1].  Only the google engine with the
"Default language" choice "(all)"" is changed by this patch.

When searching for a locate place, the result are in the expect language,
without missing results [2]:

  > When a language is not specified, the language interpretation is left up to
  > Google to decide how the search results should be delivered.

The query parameters are copied from Whoogle.  With the ``all`` language:

- add parameter ``source=lnt``
- don't use parameter ``lr``
- don't add a ``Accept-Language`` HTTP header.

The new signature of function ``get_lang_info()`` is:

    lang_info = get_lang_info(params, lang_list, custom_aliases, supported_any_language)

Argument ``supported_any_language`` is True for google.py and False for the other
google engines.  With this patch the function now returns:

- query parameters: ``lang_info['params']``
- HTTP headers: ``lang_info['headers']``
- and as before this patch:
  - ``lang_info['subdomain']``
  - ``lang_info['country']``
  - ``lang_info['language']``
