Search option doesn't work on parameter control if the control has enabled show relevant values only, but works fine when it's not. I want to have both the option, show relevant values because my list is very large and ability to search as well

Hello @jhmayank and welcome to the Quicksight community!

Can you try the filtering solution that was mentioned in this similar post? Quicksight currently can’t load more than 1,000 options.

Let me know if this helps!
