Item from website URLHi everyone, I would like to get wikidata entries of some websites. For instance if the website is bbc.com, the SPARQL query should return the entity of BBC. I built the following query according to the examples on Wikidata, however I can not get any results. I removed the filter condition, and got the official websites. But with filter, the result is empty. What could be the problem? Thanks

Use at

PREFIX wikibase: <http://wikiba.se/ontology#>
PREFIX wdt: <http://www.wikidata.org/prop/direct/>
PREFIX rdfs: <http://www.w3.org/2000/01/rdf-schema#>
PREFIX bd: <http://www.bigdata.com/rdf#>
SELECT ?item ?itemLabel ?websiteLabel WHERE {
  ?item wdt:P856 ?website.
  ?website rdfs:label ?websiteLabel .
  FILTER CONTAINS(LCASE(?websiteLabel), 'bbc.com' ).
  SERVICE wikibase:label { bd:serviceParam wikibase:language "[AUTO_LANGUAGE],en". }
}

LIMIT 10
