query-a91da3d6b89a8c947a8fde98b77779bc
to get items without any statements that have at least a german wikipedia sitelink. I want to accelerate this query to restrict it to certain QIDs. How can I filter the QID or the creation date of this item? but this is not very fast - is it possible to access the QID number diretly? FILTER(xsd:integer(strafter(str(?item),"Q")) < 2000000)I know ? schema:dateCreated like schema:dateModified - is there an alternative to ?item schema:dateModified ?date FILTER (?date < "2015-01-01T00:00:00Z"^^xsd:dateTime)I know 14:57, 29 November 2021 (UTC)) talk (Fidoez--
