Language specific search in Play Store

Is there something wrong in the title, name of app or why is the app found in English but not in Swahili? Default language is Swahili. Title and description all is in Swahili and English but the Swahili app is not found when searching Play Store.

For example:

Biblia Kimalila – it found the Malila Bible immediately
Biblia Kindali – it is not found
