if you increase the limit from 5 to say 50, then you'll get different
artists as well.
for me this isn't a problem anymore, since i already know the id's i can
simply filter them out in my script. i don't know how this lucene works,
but maybe it is possible to increase the performance if lucene would
filter this out?
still want this feature/bug reported and assigned to you? :)

fair 'nuff, i figured out that looking up a release by submitting a
releaseid (which i can get from a track lookup) will give me all the
data i need, so i can fetch all the data i need with 2 queries.


further i have a question about lucene and the "score" you get from a
lookup:
i have a mp3 named "dj tiesto - honey.mp3", and i presume "dj tiesto" is
the artist and "honey" is the title of the song. so i try the following
lookup to see if i can find some more info about this song which lack
alot of metadata:
http://musicbrainz.org/ws/1/track/?type=xml&title=honey&artist=dj%20tiesto

the very first hit got a score of 100, and that track is called "Honey
Honey" and the artist is "DJ Lucky Johal".
that i don't get the result i'm looking for (which would be this:
http://musicbrainz.org/ws/1/track/342d9aae-3208-4e46-b63d-b610e96bc334?type=xml&inc=artist)
is quite okay, because the artist of that track isn't "dj tiesto", the
title isn't just "honey" and i've generally supplied very little
metadata.
what does it mean that the first hit got a score of 100?
or rather, what does "score" mean?
