2023-03-24[mod] Google: reversed engineered & upgrade to data_type: traits_v1Markus Heiser
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 The old API suggestqueries.google.com/complete has been replaced by the async REST API: https://{subdomain}/complete/search?{args} searx/engines/google.py Reverse engineering and extensive testing ..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 Signed-off-by: Markus Heiser <markus.heiser@darmarit.de>

2022-08-01[mod] add 'Accept-Language' HTTP header to online processoresMarkus Heiser
Most engines that support languages (and regions) use the Accept-Language from the WEB browser to build a response that fits to the language (and region). - add new engine option: send_accept_language_header Signed-off-by: Markus Heiser <markus.heiser@darmarit.de>
2022-07-25[fix] google & youtube - set EU consent cookieEmilien Devos
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 [1] https://github.com/iv-org/invidious/pull/2207 [2] https://github.com/TeamNewPipe/NewPipeExtractor/issues/592 Closes: https://github.com/searxng/searxng/issues/1432

2021-06-10[enh] google engine: supports "default language"Alexandre Flament
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']`` [1] https://github.com/benbusby/whoogle-search [2] https://github.com/benbusby/whoogle-search/releases/tag/v0.5.4
