Finding string in directory

I don't know if I'm posting this on the correct category, but I'm trying to find for a string in a directory using the files search (ALT + F7) on the remote server, i.e. searching for the word 'litte' in the directory name 'green little house' I've tried several masks, documentation etc, but can't find it.

A "string" in file name or string in file contents?

Part of a directory. i.e. directory = '/green little house/' and then how to search on the word 'little'.
