Re: [Virtuoso-users] full-text search

I decided to use CONSTRUCT to make a new predicate with the search terms,
that can be inserted with SPARUL.

In case anyone's interested,
example for albums that can be looked up by artist and/or album name. It
seems to work ok with

CONSTRUCT {
    ?s <http://localhost/literals> `bif:concat(?o, " ", ?an)`
}
WHERE {
    ?s rdf:type mo:Record .
    ?s foaf:maker ?a .
    ?a foaf:name ?an .
    ?s dc:title ?o .
}

Another example for looking up movies from DBpedia, where the query can
contains terms from the title, actors or director.

CONSTRUCT {
    ?s <http://localhost/literals> `bif:concat(?o, " ", ?an, " ", ?dn)`
}
WHERE {
    ?s rdf:type dbpedia-owl:Film .
    ?s dbpprop:name ?o .
    OPTIONAL {?s dbpprop:starring ?starring .}
    OPTIONAL {?s dbpprop:director ?director . }
    OPTIONAL {?starring dbpprop:name ?an . }
    OPTIONAL {?director dbpprop:name ?dn . }
}
