Can UPnP Search also search playlists?

[timster]

Simon, is it supported for the UPnP search function to include searching playlists? These are .m3u files indexed by the server as opposed to local ones.

For example I have about 100 playlists (and growing) and I have recently had a reason to search for a particular artist's track among them to find the right playlist. The search only returns the artists/tracks that match though - so is it feasible for it to include any playlists that contain tracks or artists with the search string in the return also?

EDIT: I've also just noticed that "Tracks" returned from a search include all tracks that have the search term in the album title. Is this correct behaviour?
