Errr, of course! What a silly example I made! :-) Actually, I've been testing with LIMIT 18, where I get 34 triples back. And then I tried to trim it down to make the point clearer. I have a concept of "records" here, given that I know each title and type to be unique and exist, I expect 9 such records, so I was aware of the 2*records thing. But then I got it wrong instead. Anyway, it'd be nice of you could try the same query with LIMIT 18, that's when weirdness happens... > In addition, you may wish to abbreviate the query as follows: > FILTER (?type in ( > <http://musicbrainz.org/mm/mm-2.1#Track> , Oh, cool! But I can't remember seeing that in the SPARQL spec, is that a Virtuoso extension?
