I might be missing it but I can't find a search feature for looking up a song by title, artist, part of title, etc

I did searches through the forum for "search song title" and the like but came up empty. It seems like a fairly obvious feature, if you can remember a part of the title or the artist but not the album or song name, a lookup would be the only way to find it.

Can anybody let me know if I'm just missing it or if it's not implemented in Media Engine?

Thanks.
