And there really is no excuse, take a look at this indie dev blowing the default explorer out of the water: https://filepilot.tech

"Everything" is another that puts the default search to shame. I've also seen people who just have a script that pumps all new files into a txt file every so often and runs bruteforce ripgrep on it, which gives instant interactive results. It's really hard to imagine coming up with a search routine that is as slow and unreliable as what ships with mainstream OS file managers.
