SearXNG is a free internet metasearch engine which aggregates results from various search services and databases. Users are neither tracked nor profiled.

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%)

Differences to searx
====================
SearXNG is a fork of `searx`_. Here are some of the changes:
.. _searx: https://github.com/searx/searx
User experience
---------------
- Huge update of the simple theme:
* usable on desktop, tablet and mobile
* light and dark versions (you can choose in the preferences)
* support right-to-left languages
* `see the screenshots <https://dev.searxng.org/screenshots.html>`_
- the translations are up to date, you can contribute on `Weblate`_
- the preferences page has been updated:
* you can see which engines are reliable or not
* engines are grouped inside each tab
* each engine has a description
- thanks to the anonymous metrics, it is easier to report a bug of an engine and
thus engines get fixed more quickly
- if you don't want any metrics to be recorded, you can `disable them on the server
<https://docs.searxng.org/admin/engines/settings.html#general>`_
- administrator can `block and/or replace the URLs in the search results
<https://github.com/searxng/searxng/blob/5c1c0817c3996c5670a545d05831d234d21e6217/searx/settings.yml#L191-L199>`_
Setup
-----
- you don't need `Morty`_ to proxy the images even on a public instance
- you don't need `Filtron`_ to block bots, we implemented the builtin `limiter`_
- you get a well maintained `Docker image`_, now also built for ARM64 and ARM/v7 architectures
- alternatively we have up to date installation scripts
.. _Docker image: https://github.com/searxng/searxng-docker

----------------------
- readable debug log
- contributions to the themes are made easier, check out our `Development
Quickstart`_ guide
- a lot of code cleanup and bug fixes
- the dependencies are up to date
