Currently, every search term typed into the library query field is combined with AND relationships. It would be nice if there was a way to combine nodes with an OR relationship too. For example:
(artist:foo | artist:bar)
would match tracks that have an artist field matching either "foo" or "bar".

I think we should follow the Google syntax:

and use OR and AND

Yeah, case sensitive "OR" would be easier to type while mixing.

I think I have taken up enough for myself for the 2.2 release with the effects system improvements. Does anyone else want to volunteer for this? Uwe? If not, let's remove it from the 2.2 milestone.
