Some of the AWS UX is okay but the parameter store UX for the web console is some of the worst I've seen. It's difficult to navigate and paginate, and the search function is barely worth using. It would be amazing if they had fuzzy search on the names.
I do agree that the CloudWatch console search is like this, where you need to type out the entire string from the beginning to get it to match. But for the CloudFormation and Lambda consoles, I can just type a piece of the string I'm trying to find and all matching will just show up.
