jazzzooo f1c61921f7 [fix] engine - Crossref
Crossref was broken on result types journal-issue and component .. The old code
had lots of assumptions, and broke during parsing.  Now the assumptions are more
explicit and checked them with the API.

Markus Heiser 4c4ee13196 [fix] google engine: don't overspecify the search query to Google
The method EngineTraits.get_region(..) returns engine's region string
that **best fits** to SearXNG's locale.  This means it returns a
region (country) if only a language is set in the locale.  By example the method
returns for a locale tag `es` a region `ES`.

Google's search parameter `cr` restricts search results to documents originating
in a particular country / in case of a locale tag (language) as described above,
this argument should be unset in the query send to Google.

Emilien Devos 0fc8f99ecc [feat] new engine: bt4g added & enabled and disable by default btdigg
Disable btdigg because on most SearXNG instances, SearXNG is blocked by btdigg
due to cloudflare too many requests.

This impementation did not parse the HTML page because there is an API in
XML (RSS).  The RSS feed provides fewer data like amount of seeders/leechers and
the files in the torrent file. It's a tradeoff for a "stable" engine as the XML
from RSS content will change way less than the HTML page.

- changes the result template of zlibrary to paper.html, filling the appropriate fields
- implements language filtering for zlibrary
- implement zlibrary custom filters (engine traits)

Markus Heiser da7c30291d [fix] Google API changed
It seems that Google is rolling out a modified WEB API [1][2].

In the past there was only the UI language in the `hl` argument but nowadays it
seems a combination of the UI language and the "search region" is mixed in this
argument and the `gl` argument has been removed.  I'm very surprised that google
is starting to mix the parameters of the UI with the parameters of the search
index.

This patch modifies the get_google_info(..) function.  Beside Google-WEB this
function is also used by other Google services, here are some examples to test
region & language of ..

- Google-WEB:    `!go dragon boat :en-CA`
- Google-News:   `!gon dragon boat :en-CA`
- Google-Videos: `!gov bmw :en-CA`
- Goolge-Images  `!goi bmw :en-CA`

Markus Heiser 27369ebec2 [fix] searxng_extra/update/update_engine_descriptions.py (part 1)
Follow up of #2269

The script to update the descriptions of the engines does no longer work since
PR #2269 has been merged.

searx/engines/wikipedia.py
==========================

1. There was a misusage of zh-classical.wikipedia.org:

   - `zh-classical` is dedicate to classical Chinese [1] which is not
     traditional Chinese [2].

   - zh.wikipedia.org has LanguageConverter enabled [3] and is going to
     dynamically show simplified or traditional Chinese according to the
     HTTP Accept-Language header.

2. The update_engine_descriptions.py needs a list of all wikipedias.  The
   implementation from #2269 included only a reduced list:

   - https://meta.wikimedia.org/wiki/Wikipedia_article_depth
   - https://meta.wikimedia.org/wiki/List_of_Wikipedias

searxng_extra/update/update_engine_descriptions.py
==================================================

Before PR #2269 there was a match_language() function that did an approximation
using various methods.  With PR #2269 there are only the types in the data model
of the languages, which can be recognized by babel.  The approximation methods,
which are needed (only here) in the determination of the descriptions, must be
replaced by other methods.

This PR does no functional change it is just an attempt to make more clear in
the code, what a default category is and what a subcategory is.  The previous
name 'others' leads to confusion with the **category 'other'**.

If a engine is not assigned to a category, the default is assigned::

    DEFAULT_CATEGORY = 'other'

If an engine has only one category and this category is shown as tab in the user
interface, this engine has no further subgrouping::

    NO_SUBGROUPING = 'without further subgrouping'

Markus Heiser 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

Markus Heiser c80e82a855 [mod] DuckDuckGo: reversed engineered & upgrade to data_type: traits_v1
Partial reverse engineering of the DuckDuckGo (DDG) engines including a
improved language and region handling based on the enigne.traits_v1 data.

- DDG Lite
- DDG Instant Answer API
- DDG Images
- DDG Weather

docs/src/searx.engine.duckduckgo.rst:
  Online documentation of the DDG engines (make docs.live)

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

  - "duckduckgo" (WEB),
  - "duckduckgo images" and
  - "duckduckgo weather"

  and remove data from obsolete data type "supported_languages".

searx/autocomplete.py:
  Reversed engineered Autocomplete from DDG.  Supports DDG's languages.

searx/engines/duckduckgo.py:
  - fetch_traits():  Fetch languages & regions from DDG.

  - get_ddg_lang(): Get DDG's language identifier from SearXNG's locale.  DDG
    defines its languages by region codes.  DDG-Lite does not offer a language
    selection to the user, only a region can be selected by the user.

  - Cache ``vqd`` value: The vqd value depends on the query string and is needed
    for the follow up pages or the images loaded by a XMLHttpRequest (DDG
    images).  The ``vqd`` value of a search term is stored for 10min in the
    redis DB.

  - DDG Lite engine: reversed engineered request method with improved Language
    and region support and better ``vqd`` handling.

searx/engines/duckduckgo_definitions.py: DDG Instant Answer API
  The *instant answers* API does not support languages, or at least we could not
  find out how language support should work.  It seems that most of the features
  are based on English terms.

searx/engines/duckduckgo_images.py: DDG Images
  Reversed engineered request method.  Improved language and region handling
  based on cookies and the enigne.traits_v1 data.  Response: add image format to
  the result list

searx/engines/duckduckgo_weather.py: DDG Weather
  Improved language and region handling based on cookies and the
  enigne.traits_v1 data.

Markus Heiser e9afc4f8ce [mod] Startpage: reversed engineered & upgrade to data_type: traits_v1
One reason for the often seen CAPTCHA of the Startpage requests are the
incomplete requests SearXNG sends to startpage.com: this patch is a complete new
implementation of the ``request()`` function, reversed engineered from the
Startpage's search form.  The new implementation:

- use traits of data_type: traits_v1 and drop deprecated data_type: supported_languages
- adds time-range support
- adds save-search support
- fix searxng/searxng/issues 1884
- fix searxng/searxng/issues 1081 --> improvements to avoid CAPTCHA

In preparation for more categories (News, Images, Videos ..) from Startpage, the
variable ``startpage_categ`` was set up.  The default value is ``web`` and other
categories from Startpage are not yet implemented.
