In Presearch there are languages for the UI and regions for narrowing down the
search. With this change the SearXNG engine supports a search by region. The
details can be found in the documentation of the source code.
To test, you can search terms like::
!presearch bmw :zh-TW
!presearch bmw :en-CA
1. You should get results corresponding to the region (Taiwan, Canada)
2. and in the language (Chinese, Englisch).
3. The context in info box content is in the same language.
Exceptions:
1. Region or language is not supported by Presearch or
2. SearXNG user did not selected a region tag, example::
!presearch bmw :en
