If artist name contains feat and get no matches strip out and try again

i.e

query=artist:(Natalie~0.7 AND La AND Rose~0.7 AND feat. AND Jeremih~0.7) AND track:"Somebody" AND src:1

doesnt match because Jermiah is part of the song title in MusicBrainz not the artist credit field for this particular song. In the sytle guidelines should be part of Artist credit but this hasnt ahhpened yet for many tracks.
