KDE search is super good, if you're referring to krunner. It searches everything, bookmarks, open tabs, filenames, paths, and even file contents. And it's really fast.

You have to turn the file indexer on or install it if you don't have it. Try `baloo status` or `baloo6 status`. Poke around in setting too so you can index what you need and not temp files.
