I understand the wikidata SPARQL label service only fetches the labels, but does not allow to search/filter on them; labels are also available in regulare rdfs:label on which a FILTER can be made.
However I would like to do full-text search over labels, to e.g. feed an autocomplete search field, actually just like the usual top-right wikidata search field does. I would also be interested to combine this with a criteria on "instance of", to search only on instances of a given class.
Can I do that efficiently using the Wikidata SPARQL service ? or is there a separate API I could use ? (exemple welcome)
