Can I use it with multiple search terms then?
I tried with this where leonardo is in dbpedia-owl:starring and gangs is in
dbpprop:name, but it doesn't return any results.
SELECT DISTINCT ?s ?p ?o ?mscore
WHERE { ?s ?p ?o . ?s rdf:type dbpedia-owl:Film . FILTER( ?p in (
dbpedia-owl:starring, dbpprop:name ) ) . ?o bif:contains 'leonardo AND
gangs' option (score ?mscore) } ORDER BY DESC(?mscore)
Best,
Mats
