The search for toponyms does not work well

[Korb]

Describe the issue
When I enter, for example, "Подгорица, Черногория" (Wikipedia) or "Podgorica, Montenegro" (Wikipedia) into the application's search bar, I always get the same "Sorry, we didn't find anything. Try changing your search terms." (in the English version of the application it probably looks something like "Unfortunately, we didn't find anything. Try changing your search terms.")

At the same time, when using OSM search in the SAS.Planet application, the settlement is found both when using the Cyrillic alphabet and when using the Latin alphabet.

Steps to reproduce

1. Open organicmaps
2. Click on the second icon below, with the image of a magnifying glass
3. Type the text "Подгорица, Черногория" or "Podgorica, Montenegro" (without quotes)
4. Read the message about no results

Expected behaviour
I expect to see, at a minimum, the name of the administrative center of the municipality. Or better yet, a list of: a locality, an airport of the same name, a railway station of the same name, a stadium of the same name and a football club of the same name.

While "sr" (Serbian Cyrillic) language is supported in the map data, it looks like it is not enabled in indexer/categories_holder.hpp for the search (and is absent in data/cagegories.txt). Any help with adding translations is appreciated: https://github.com/organicmaps/organicmaps/blob/master/docs/TRANSLATIONS.md

Moreover, I found that the search is not stable. Repeat the sequence (Montenegro is not downloaded):

• "Подгорица" // ok
• "Подгорица Montenegro" // bad
• "Подгорица" (delete Montenegro) // bad ?! again
