Hi, i have a problem with the bif:contains function. It does not work and i could find if there is any configuration options to enable it.
*Server/Virtuoso: version 06.01.3127, on Linux (x86_64-pc-linux-gnu), Single Edition* *SPARQL Endpoint: http://el.dbpedia.org/sparql* For the same query, the bif:contains function does not return any results, while with Filter regex does e.g. PREFIX rdfs: <http://www.w3.org/2000/01/rdf-schema#> A) select ?o ?l where { ?o rdfs:label ?l. ?l bif:contains "Linux". } B) select ?o ?l where { ?o rdfs:label ?l. FILTER(regex(?l,"Linux")). } I tested the (A) option in the dbpedia.org/sparql and it works fine Execute urls A) http://el.dbpedia.org/sparql?default-graph-uri=http%3A%2F%2Fel.dbpedia.org&should-sponge=&query=PREFIX+rdfs%3A+%3Chttp%3A%2F%2Fwww.w3.org%2F2000%2F01%2Frdf-schema%23%3E%0D%0A%0D%0Aselect+%3Fo+%3Fl+where+{%0D%0A%3Fo+rdfs%3Alabel+%3Fl.%0D%0A%3Fl+bif%3Acontains+%22Linux%22.%0D%0A}&format=text%2Fhtml&debug=on&timeout= B) http://el.dbpedia.org/sparql?default-graph-uri=http%3A%2F%2Fel.dbpedia.org&should-sponge=&query=PREFIX+rdfs%3A+%3Chttp%3A%2F%2Fwww.w3.org%2F2000%2F01%2Frdf-schema%23%3E%0D%0A%0D%0Aselect+%3Fo+%3Fl%0D%0Awhere+{%0D%0A%3Fo+rdfs%3Alabel+%3Fl.%0D%0AFILTER%28regex%28%3Fl%2C%22Linux%22%29%29.%0D%0A}&format=text%2Fhtml&debug=on&timeout= -- Kontokostas Dimitris
