Great to learn about these features/extensions. However, I'm confused by
the results in Lucas's example query for WikibaseCirrusSearch. How is the
string "einst" being matched here?
Thanks,
Tim

If you use regular search rather than entity search,
you can use
WikibaseCirrusSearch
<https://www.mediawiki.org/wiki/Special:MyLanguage/Help:Extension: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…
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
<https://query.wikidata.org/#SELECT%20DISTINCT%20%3Fperson%20%3FpersonLabel%20WHERE%20%7B%0A%20%20SERVICE%20wikibase%3Amwapi%20%7B%0A%20%20%20%20%20%20bd%3AserviceParam%20wikibase%3Aapi%20%22EntitySearch%22%20.%0A%20%20%20%20%20%20bd%3AserviceParam%20wikibase%3Aendpoint%20%22www.wikidata.org%22%20.%0A%20%20%20%20%20%20bd%3AserviceParam%20mwapi%3Asearch%20%22einst%22%20.%0A%20%20%20%20%20%20bd%3AserviceParam%20mwapi%3Alanguage%20%22en%22%20.%0A%20%20%20%20%20%20%3Fperson%20wikibase%3AapiOutputItem%20mwapi%3Aitem%20.%0A%20%20%7D%0A%20%20%3Fperson%20wdt%3AP31%20wd%3AQ5.%0A%20%20%0A%20%20%0A%20%20SERVICE%20wikibase%3Alabel%20%7B%20bd%3AserviceParam%20wikibase%3Alanguage%20%22%5BAUTO_LANGUAGE%5D%2Cen%22.%20%7D%0A%20%20%0A%20%20%0A%7D%20ORDER%20BY%20DESC(%3Fperson)%20LIMIT%2020>
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
