"Terminal-indpendant searches" is the best way I could think to describe:
Searching for a string which exists anywhere in a database field, not just at the begining.

Maybe "context-free searches" or "substring searches"? Regardless, I swear I have song with "Mussolini" in the title, but I don't know where or by whom. Of course, a Windows file search found nothing, but it might be cool if the empeg could substring search also.

Which leads to another thought: themed playlists via searches. "I want to hear all songs with the word 'Monday' in the title." A fun exercise for home use, but doesn't work on the empeg for the same terminal-dependant (aka: always starts at the begining) searches.

Not a real request, just an idea.
