We experimented with it sometime ago for our https://curiosity.ai app, initial training on your data was a bit heavy (at the time, probably fine by today's standards) but nice results if you had enough files. Needs to be done with care as for small datasets as there's not enough info for a model to learn and you end up introducing more noise than anything.

There are some Spotlight replacements on Mac that I’ve been meaning to try out, but not sure they do this specifically.

I personally use Everything by Voidtools.

Remembering the exact name is great, but I find using *.docx combined with sorting by date is often good enough.
