[BUG] Unable to search for index patterns on Discover Menu through keywords

[vmm-afonso]

Describe the bug

I can't search for index patterns on the Discover Menu simply by typing keywords and get relevant search results…

It just turns those keywords bold (which makes it a bit easier to identify when looking for the right index pattern) but I still have to scroll down and look for the right index pattern.

I got the confirmation from a member on the opensearch-forum that this wasn't an issue in the previous version of Discovery and he gave me the green light to report this issue further

To Reproduce
Steps to reproduce the behavior:

1. Go to the 'Discover' Menu
2. Try searching for any index pattern
3. Notice that by pressing enter you're not getting relevant search results, you're just seeing the parts of the indices that match your search turning bold

Expected behavior
I was expecting to get a list of indices that matched my search

OpenSearch Version
2.11.1

Dashboards Version
2.11.1
