Problem with QualifiersHello, i have got a Problem with qualifiers. I wrote a Sparql, where the Catalogue-Text starts with NGC. It works. But i want to see it only, when it has no Qualifier. How can i do that ?

Use at

PREFIX wikibase: <http://wikiba.se/ontology#>
PREFIX wdt: <http://www.wikidata.org/prop/direct/>
PREFIX bd: <http://www.bigdata.com/rdf#>
SELECT ?item ?itemLabel ?text
WHERE
{
  ?item wdt:P528 ?text.
  FILTER(STRSTARTS(?text, "NGC")).
  SERVICE wikibase:label { bd:serviceParam wikibase:language "de". }

}
