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 The old API suggestqueries.google.com/complete has been replaced
by the async REST API: https://{subdomain}/complete/search?{args}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

Partial reverse engineering of the DuckDuckGo (DDG) engines including a
improved language and region handling based on the enigne.traits_v1 data.

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

The implementation of the etools engine is poor. No date-range support, no
language support and it is broken by a CAPTCHA.
etools is a metasearch engine, the major search engines it supports (google,
bing, wikipedia, Yahoo) are already available in SeaarXNG.
While etools does support several engines we currently don't support directly,
support for them should be added directly to SearXNG if there is demand.
In practice: in SearXNG the worse etools results will be mixed with good results
from other engines we have (as long as there is no captcha).
At best case, what we win with etools is in e.g. results from de.ask.com in a
query from a german request .. in all other cases worse results are bubble up in
SearXNG's result list.

The general category is the category that is searched by default.
From a privacy standpoint it doesn't make sense to send all general
queries to specialized search engines that cannot deal with those
queries anyway.
Previously we didn't have a good place to put search engines that don't
fit into any of the tab categories. This commit automatically puts
search engines that don't belong to any tab category in an "other"
category, that is only displayed in the user preferences (and not above
search results).
Previously all categories were displayed as search engine tabs.
This commit changes that so that only the categories listed under
categories_as_tabs in settings.yml are displayed.
This lets us introduce more categories without cluttering up the UI.
Categories not displayed as tabs can still be searched with !bangs.

Languages are supported by mapping the language to a domain. If domain is not
found in :py:obj:`lang2domain` URL ``<lang>.search.yahoo.com`` is used.

The key of the dictionary 'searx.data.ENGINES_LANGUAGES' is the *engine name*
configured in settings.xml. When multiple engines are configured to use the
same origin engine (e.g. `engine: google`)::
- name: google
engine: google
use_mobile_ui: false
...
- name: google italian
engine: google
use_mobile_ui: false
language: it
...
- name: google mobile ui
engine: google
shortcut: gomui
use_mobile_ui: true
There exists no entry for ENGINES_LANGUAGES[engine.name] (e.g. `name: google
mobile ui` or `name: google italian`). This issue can be solved by recreate the
ENGINES_LANGUAGES::
make data.languages
But this is nothing an SearXNG admin would like to do when just configuring
additional engines, since this just doubles entries in ENGINES_LANGUAGES and
BTW: `make data.languages` has various external requirements which might be not
installed or not available, on a production host.
With this patch, if engine.name fails, ENGINES_LANGUAGES[engine.engine] is used
to get the engine.supported_languages (e.g. `google` for the engine named
`google mobile`).
For an engine, when there is `language: ...` in the YAML settings, the engine
supports only one language, in this case engine.supported_languages should
contains this value defined in settings.yml (e.g. `it` for the engine named
`google italian`).

Implement a scrapper for DuckDuckGo-Lite [1]. The existing DuckDuckGo [2]
engine does not support paging. DuckDuckgo-Lite is much faster, less verbose
and does have a paging option (reversed engineered from the input form of [1]).

If there is no write access, there is no need for global. Remove global
statement if there is no assignment.
global-variable-not-assigned:
Using global for names but no assignment is done Used when a variable is
defined through the "global" statement but no assignment to this variable is
done.
In Pylint 2.11 the global-variable-not-assigned checker now catches global
variables that are never reassigned in a local scope and catches (reassigned)
functions [1][2]

the openstreetmap engine imports code from the wikidata engine.
before this commit, specific code make sure to copy the logger variable to the wikidata engine.
with this commit searx.engines.load_engine makes sure the .logger is initialized.
The implementation scans sys.modules for module name starting with searx.engines.
close#298
This is a workaround: inside engine code, any call to function in another engine can crash
since the logger won't be initialized except if it is done explicitly.
Instead of raising an exception and therefore hiding all results of the engine.
It make sense to remove that requirement in order to allow the implementation of
search engines that do not always have a description. In fact some search
engines that in 99% of the case have a description like Brave Search or Mojeek
crash completely if they for some reason included a result with no description.
To test this patch try Mojeek:
!mjk xyz
before and after the patch.

The implementation uses the Qwant API (https://api.qwant.com/v3). The API is
undocumented but can be reverse engineered by reading the network log of
https://www.qwant.com/ queries.
This implementation is used by different qwant engines in the settings.yml::
- name: qwant
categories: general
...
- name: qwant news
categories: news
...
- name: qwant images
categories: images
...
- name: qwant videos
categories: videos

In the EU there exists a "General Data Protection Regulation" [1] aka GDPR (BTW:
very user friendly!) which requires consent to tracking. To get the consent
from the user, google-news requests are redirected to confirm and get a CONSENT
Cookie from https://consent.google.de/s?continue=...
This patch adds a CONSENT Cookie to the google-news request to avoid
redirection.
The behavior of the CONTENTS cookies over all google engines seems similar but
the pattern is not yet fully clear to me, here are some random samples from my
analysis ..
Using common google search from different domains::
google.com: CONSENT=YES+cb.{{date}}-14-p0.de+FX+816
google.de: CONSENT=YES+cb.{{date}}-14-p0.de+FX+333
google.fr: CONSENT=YES+srp.gws-{{date}}-0-RC2.fr+FX+826
When searching about videos (google-videos)::
google.es: CONSENT=YES+srp.gws-{{date}}-0-RC2.es+FX+076
google.de: CONSENT=YES+srp.gws-{{date}}-0-RC2.de+FX+171
Google news has only one domain for all languages::
news.google.com: CONSENT=YES+cb.{{date}}-14-p0.de+FX+816
Using google-scholar search from different domains::
scholar.google.de: CONSENT=YES+cb.{{date}}-14-p0.de+FX+333
scholar.google.fr: does not use such a cookie / did not ask the user
scholar.google.es: does not use such a cookie / did not ask the user
Interim summary:
Pattern is unclear and I won't apply the CONSENT cookie to all google engines.
More experience is need before we generalize the CONSENT cookies over all
google engines.

Since we added

there is a KeyError: 'hl in request,error pattern::

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']``
