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'

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)

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.

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.

Implementations of the *traits* of the engines.
Engine's traits are fetched from the origin engine and stored in a JSON file in
the *data folder*. Most often traits are languages and region codes and their
mapping from SearXNG's representation to the representation in the origin search
engine.
To load traits from the persistence::
searx.enginelib.traits.EngineTraitsMap.from_data()
For new traits new properties can be added to the class::
searx.enginelib.traits.EngineTraits
.. hint::
Implementation is downward compatible to the deprecated *supported_languages
method* from the vintage implementation.
The vintage code is tagged as *deprecated* an can be removed when all engines
has been ported to the *traits method*.

* fix type in settings.yml: replace suspend_times by suspended_times
* always use delay defined in settings.yml:
* HTTP status 402 and 403: read the value from settings.yml instead of using the hardcoded value of 1 day.
* startpage engine: CAPTCHA suspend the engine for one day instead of one week
This patch is to hardening the parsing of the bing response:
1. To fix [2087] check if the selected result item contains a link, otherwise
skip result item and continue in the result loop. Increment the result
pointer when a result has been added / the enumerate that counts for skipped
items is no longer valid when result items are skipped.
To test the bugfix use: ``!bi :all cerbot``
2. Limit the XPath selection of result items to direct children nodes (list
items ``li``) of the ordered list (``ol``).
To test the selector use: ``!bi :en pontiac aztek wiki``
.. in the result list you should find the wikipedia entry on top,
compare [2068]
[2087] https://github.com/searxng/searxng/issues/2087
[2068] https://github.com/searxng/searxng/issues/2068
Modify the XPath selector to get the wikipedia result plus small fixes.
About result content: especially with the Wikipedia result, we'd get several
paragraph elements, only the first paragraph would be taken and displayed on the
search result
- fix issue reported #1809
- filter out `None` value from issn and isbn list
- add comments (from publicationName)

These HTTP status are seen an empty result list.
In other cases an exception is thrown as usual.
Previously raise_for_httperror were ignoring all HTTP error,
which make defective engines invisible in the stats.
The request function should not request a language (aka locale) that is not

The existing searx.utils.match_language function is unsuitable for this purpose,
it is replaced by function searx.locales.get_engine_locale that is based on the

Just in case if content is None, the original code will skip extract_text(), and
just append the None value to 'content'. So just add allow_none=True, and this

- improve the request function and filter by language & country
- implement time_range_support & safesearch
- add more fields to the response from dailymotion (allow_embed, length)
- better clean up of HTML tags in the 'content' field.
