.. hint::

The *SearXNG locale* string has to be known by babel!

If there is no direct 1:1 mapping, this functions tries to narrow down
|

engine's language (locale). If no value can be determined by these
|
||||
approximation attempts the ``default`` value is returned.
|
||||
|
||||
Assumptions:
|
||||
|
||||
A. When user select a language the results should be optimized according to
|
||||
the selected language.
|
||||
|
||||
B. When user select a language and a territory the results should be
|
||||
optimized with first priority on terrirtory and second on language.
|
||||
|
||||
First approximation rule (*by territory*):
|
||||
|
||||
When the user selects a locale with terrirtory (and a language), the
|
||||
territory has priority over the language. If any of the offical languages
|
||||
in the terrirtory is supported by the engine (``engine_locales``) it will
|
||||
be used.
|
||||
|
||||
Second approximation rule (*by language*):
|
||||
|
||||
If "First approximation rule" brings no result or the user selects only a
|
||||
language without a terrirtory. Check in which territories the language
|
||||
has an offical status and if one of these territories is supported by the
|

engine.
