This is expected behavior! We have replicated functionality from Google search to normalize queries by changing them to lowercase. If this is something that is important to your client, we can discuss the option with our Product team.
Thank you for the quick response. That makes total sense, I just wanted to make sure I wasn’t missing anything on my side. Really appreciate the clarification!
I just noticed a related issue that might require a deeper look:
It appears that query suggestions are being stripped of Umlaut-type characters (e.g. “ä” becomes “a”). This is problematic for languages like German where “ä” and “a” are distinct letters and should not be normalized.
