Need help to find items without description in special languageMoin Moin together, the SPARQL and I, long story. All I want is to find items without description but with a property in a language, this is my example, could somebody help me? (I find too few objects!)

Use at

PREFIX wikibase: <http://wikiba.se/ontology#>
PREFIX wdt: <http://www.wikidata.org/prop/direct/>
PREFIX wd: <http://www.wikidata.org/entity/>
PREFIX schema: <http://schema.org/>
PREFIX bd: <http://www.bigdata.com/rdf#>
SELECT DISTINCT ?item ?itemLabel
WHERE
{
    ?item wdt:P31 wd:Qxxxxxxx .
    OPTIONAL { ?item schema:description ?itemDescription  }
    FILTER (!BOUND(?itemDescription))
    SERVICE wikibase:label { bd:serviceParam wikibase:language "de"}
}
LIMIT 100
