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*.

From the analyse of @9Ninety [1] we know that DDG (and may be other engines / I
have startpage in mind) does some kind of TLS fingerprint to block bots.
This patch shuffles the default ciphers from httpx to avoid a cipher profile
that is known to httpx (and blocked by DDG).

When the user choose "Auto-detected", the choice remains on the following queries.
The detected language is displayed.
For example "Auto-detected (en)":
* the next query language is going to be auto detected
* for the current query, the detected language is English.
This replace the autodetect_search_language plugin.
Tineye becomes active as soon as a https:// signature is found in the search
term, but most of the time a reverse image search is not requested when a URL is
specified, often the URL is just from a C&P.
The frequent requests to tineye lead in the end to the SearXNG instance being
blocked by tineye and the user seeing unexpected error messages.

Phone sized devices continue without this widget as deterministic

The widget is agnostic to the actual amount of pages there are that one

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items is no longer valid when result items are skipped.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
This changes the Suggestions to be a single column, not a wrapping row,
changing the input to be incapable of overflowing into visually adjacent
elements.
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

Default behavior of urllib.parse_qs is to discard blank values, causing a preference of none to be deserialized as undefined, using the instance default rather than the selected preference.
redis.Redis.from_url(url) doesn't check if the url is valid
Before this commit: actual error are detected later when the client is actually used.
With this commit, client() makes sure to return a valid Redis client or None.
Also, the code makes sure not to log the password of the Redis URL
settings.yml:
* The default URL was unix:///usr/local/searxng-redis/run/redis.sock?db=0
* The default URL is now "false"
The default URL makes the log difficult to deal with:
if the admin didn't install a Redis instance, the logs record a false error.
It worked before because SearXNG initialized the Redis connection when the limiter started.
In this commit, SearXNG initializes Redis in searx/webapp.py
so various components can use Redis without taking care of the initialization step.

no_result_for_http_status contains a list of HTTP status.
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.
With the POST method, autocomplete.js does not URL encode the values.
For example "1+1" is sent as "1+1" which is read as "1 1" since space are URL encoded with a plus.
There is no clean way to fix the bug since autocomplete.js seems abandoned.

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
methods from the babel package.

languages 8aka locales) not supported by qwant.
Signed-off-by: Markus Heiser <markus.heiser@darmarit.de>
The match_language function sometimes returns incorrect results which is why a
new function get_engine_locale is required.
A bugfix of the match_language is not easily possible, because there is almost
no documentation for it and already the call parameters are undefined. E.g. the
function processes values like the ones from yahoo::
"yahoo": [
"ar",
...
"zh_chs",
"zh_cht"
]
The get_engine_locale has been documented in detail, there is a clear
description of the assumptions as well as the requirements and approximation
rules (read doc-string for more details)::
Argument ``engine_locales`` is a python dict that maps *SearXNG locales* to
corresponding *engine locales*:
<engine>: {
# SearXNG string : engine-string
'ca-ES' : 'ca_ES',
'fr-BE' : 'fr_BE',
'fr-CA' : 'fr_CA',
'fr-CH' : 'fr_CH',
'fr' : 'fr_FR',
...
'pl-PL' : 'pl_PL',
'pt-PT' : 'pt_PT'
}
.. hint::
The *SearXNG locale* string has to be known by babel!
In the following you will find a comparison:
>>> import babel.languages
>>> from searx.utils import match_language
>>> from searx.locales import get_engine_locale
Assume we have an engine that supports the follwoing locales:
>>> lang_list = {
... "zh-CN": "zh_CN",
... "zh-HK": "zh_HK",
... "nl-BE": "nl_BE",
... "fr-CA": "fr_CA",
... }
Assumption:
A. When a user selects a language the results should be optimized according to
the selected language.
B. When user selects a language and a territory the results should be
optimized with first priority on territory and second on language.
----
Example: (Assumption A.)
A user selects region 'zh-TW' which should end in zh_HK
hint:
CN is 'Hans' and HK ('Hant') fits better to TW ('Hant')
>>> get_engine_locale('zh-TW', lang_list)
'zh_HK'
>>> lang_list[match_language('zh-TW', lang_list)]
'zh_CN'
----
Example: (Assumption A.)
A user selects only the language 'zh' which should end in CN
>>> get_engine_locale('zh', lang_list)
'zh_CN'
>>> lang_list[match_language('zh', lang_list)]
'zh_CN'
----
Example: (Assumption B.)
A user selects region 'fr-BE' which should end in nl-BE
hint:
priority should be on the territory the user selected. If the user
prefers 'fr' he will select 'fr' without a region tag.
>>> get_engine_locale('fr-BE', lang_list, default='unknown')
'nl_BE'
>>> match_language('fr-BE', lang_list, fallback='unknown')
'fr-CA'
----
Example: (Assumption A.)
A user selects only the language 'fr' which should end in fr_CA
>>> get_engine_locale('fr', lang_list)
'fr_CA'
>>> lang_list[match_language('fr', lang_list)]
'fr_CA'
----
The difference in priority on the territory is best shown with a engine that
supports the following locales:
>>> lang_list = {
... "fr-FR": "fr_FR",
... "fr-CA": "fr_CA",
... "en-GB": "en_GB",
... "nl-BE": "nl_BE",
... }
----
Example: (Assumption A.)
A user selects only a language
>>> get_engine_locale('en', lang_list)
'en_GB'
>>> match_language('en', lang_list)
'en-GB'
hint: the engine supports fr_FR and fr_CA since no territory is given, fr_FR
takes priority ..
>>> get_engine_locale('fr', lang_list)
'fr_FR'
>>> lang_list[match_language('fr', lang_list)]
'fr_FR'
----
Example: (Assumption B.)
A user selects region 'fr-BE' which should end in nl-BE
>>> get_engine_locale('fr-BE', lang_list)
'nl_BE'
>>> lang_list[match_language('fr-BE', lang_list)]
'fr_FR'
----
If the user selects a language and there are two locales like the following:
>>> lang_list = {
... "fr-BE": "fr_BE",
... "fr-CH": "fr_CH",
... }
>>>
>>> get_engine_locale('fr', lang_list)
'fr_BE'
>>> lang_list[match_language('fr', lang_list)]
'fr_BE'
Looks like both functions return the same value, but match_language depends on the
order of the dictionary (which is not predictable):
>>> lang_list = {
... "fr-CH": "fr_CH",
... "fr-BE": "fr_BE",
... }
>>> get_engine_locale('fr', lang_list)
'fr_BE'
>>> lang_list[match_language('fr', lang_list)]
'fr_CH'
>>>
The get_engine_locale selects the locale by looking at the "population percent"
and this percentage has an higher amount in BE (68.%) compared to CH (21%)

Neeva is "the world's first ad-free, private search engine" and uses data from Apple, Bing, Yelp and "others".
They claim to crawl "hundreds of millions" of URLs a day (https://twitter.com/Neeva/status/1536447373903335426).
Some HTTP-Clients do have issues with the ``opensearch.xml`` from SearXNG
(related [1][2]) while other OpenSearch descriptions[3] (e.g. from qwant) work
flawles.
Inspired by the OpenSearch description from qwant and with informations from the
specification[4] the ``opensearch.xml`` has been *improved*.
- convert `<Url>` methods from lower case to upper case (`POST`|`GET`)
- add `<moz:SearchForm>` and `xmlns:moz="http://www.mozilla.org/2006/browser/search/"`
- add `<Query role="example" searchTerms="SearXNG" />` [4]
OpenSearch description documents should include at least one Query element of
`role="example"` that is expected to return search results. Search clients may
use this example query to validate that the search engine is working properly.
- modified `<LongName>` to SearXNG
- modified `<Description>` the word 'hackable' scares uninitiated users and was removed
- add the `type="image/png"` to `<Image>`
Test can be done by::
make run
Visit http://127.0.0.1:8888/ and add the search engine to your WEB-Browser /
test with different WEB-Browser from desktop and Smartphones (are there any iOS
user here, please test on Safari and Chrome).
