On Windows I use:
- Voidtools Everything for search by name/metadata.
- DocFetcher (open-source version) for search by file contents.
Everything is excellent, but DocFetcher could be improved.

I use directories to organize my files.
A few approaches combined make for a very "shallow" search whenever I need something
- Johnny Decimal (https://johnnydecimal.com/) to structure folders
- agkozak/zsh-z: Jump quickly to directories that you have visited "frecently." A native Zsh port of z.sh with added features. (https://github.com/agkozak/zsh-z)
- catfish for searching (https://docs.xfce.org/apps/catfish/start)
The 2nd and 3rd component have many alternatives across platforms.
