If you use regular search rather than entity search, you can use WikibaseCirrusSearch search keywords like "haswbstatement:P31=Q5". Note that this uses a different kind of search, though – I think it only matches full words (after stemming and other transformations?), not prefixes. Query Link

Forgot to mention: you can do the same search using the API only: https://www.wikidata.org/w/api.php?action=wbsearchentities&search=einst&language=en&format=json

But not sure you can easily filter the results by "instance of".

Hello Thomas,

You can perform a full text search with the API, but not yet with SPARQL AFAIK. However, it is possible to call the API in a SPARQL query. For example, here is a query that looks for "human (Q5)"  whose label contains the string "einst".

Hope this helps,

Hello

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)

Thanks

Thomas
