For many users, it is a strict downgrade that was forced on them against their consent.
The functionality of Find Any File was built in to Mac OS 9 and earlier. It was rock-solid reliable. So of course Apple removed it and now to get reliable search you have to use a third-party tool. Or 'find' in the Terminal.
That's revolutionary.
I made my own “pseudo spotlight” and mapped it to ⌘-Space specifically for this. It just goes against old fashioned locate/updatedb, but with a very quick check against /Applications first + running the search query through bc and if it’s valid syntax, showing the math result.
