My guess would be that because of SPARQL bottom-up semantics, ?prefLabel is undefined at the point where you are applying it. Try moving it out of OPTIONAL.

There are plenty of matches in store and this returns them (case sensitive match) SELECT ?prefLabel ?s2 WHERE { GRAPH <http://www.lingsoft.fi/somegraph> { ?s skos:prefLabel ?prefLabel . } OPTIONAL { GRAPH ?graph { ?s2 skos:prefLabel ?prefLabel } } } Im I using FILTER wrong way or could it be a bug in search engine?
