Thanks again to Ettore, but I immediately found another timeout problem
when I just added a FILTER to find all the articles with the word "biokis"
in the title
SELECT ?istanza_di ?instanza_diLabel WHERE {
?istanza_di wdt:P31 wd:Q13442814.
?istanza_di rdfs:label ?instanza_diLabel.
FILTER((LANG(?instanza_diLabel)) = "en").
FILTER(CONTAINS(LCASE(?instanza_diLabel), "biokis"))
}
LIMIT 100
At least one article should be returned:
https://www.wikidata.org/wiki/Q57202937
but I got a timeout.
Thanks to anybody that can help
Fabrizio
