Expanded Search Capabilities

The placeholder text in the search box says “Search all the things” but it does not search all the things!

It would be nice to be able (even with an additional option) search exactly that - “all the things.” For example, I had a need to search across multiple ticket descriptions/comments/responses for certain text. Unfortunately the search does NOT search all the things and it was not returning any results for content that I know exists in ticket descriptions. (My use case was for tracking repetitiveness within tickets/incidents.) I have not fully tested to see which other modules is lacking this functionality, but if it is intended to search all the things then I would expect results from all the things.
