Case Sensitive Searches

[Atlas]

I am running a multilingual app, and users are also multilingual .  And all users have permission to add new products. Every user makes entries in a different way and I can not restrict users to making entries just for ENGLISH letters. The problem is that some items are don't seen in the search.  And also I realized that mobile and desktop search results are different for the exact same word. I shared all searches from mobile and desktop FYI.
