my problem is this.
There are posts with string "ÖZYALIN"
When I search it as ÖZYALIN results appear without any issue. But when I do that search as Özyalın or özyalın results doesn't show.
It doesn't happen when string doesn't have any unique Turkish character. Forexample if you search for sting MAYAN you can use MAYAN, Mayan or mayan and results appear without and issue.
