Highly recommend Everything instead. It's so freaking fast, can search by keywords, can sort by time change to see what files are being touched in real time, can search any "cloud" file if you have them locally ... And no ads!
(disclaimer: I work at Google, but nothing related to this app)
But Google App is more than a search bar for filesystem, it's like Perplexity
That said, I do wonder why Linux gone search is always so slow even on indexed files.
Huge exaggeration.
It just needs to be ext4, and like 90% would be covered b you by that.
For remaining 10%, (and only if you care), XFS and btrfs would be more than enough.
