The problem with search filters

[Maksim Donchenko]

Hi to all. I'm trying to upgrade to Dspace 7.5 and noticed that the filters on the advanced search page don't work correctly with Cyrillic. They do not issue suggestions when you enter a query in Cyrillic characters. For example, to find an author written in Cyrillic, the search query must completely match the way it is written in the database, but if the author is written in Latin, the filter works and issues suggestions based on the search query entered in the field. Is it possible to fix it?

Thank you and kind regards Maksim
