Search for a file in a specific backup.

There are times that I get a request for restore and not given the whole path so I can find the file and restore it. What I'm given is the mapped path on the end user's computer. To make things quicker, is there a way that I could search the specific backup or a specific drive on the backup for a filename? I've tried the "search backups" option in back, archive and restore and don't get any results.
