Thanks ag
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.

I noticed I could also specify AUTO_LANGUAGE in the filter, and it is
still a quick query:
SELECT ?istanza_di ?instanza_diLabel WHERE {
?istanza_di wdt:P31 wd:Q13442814.
?istanza_di
Thanks!

Hello Fabrizio,
It seems that the problem comes from SERVICE wikibase:label. As said in
another discussion, the query executes in less than one second if you rewrite
it in this way
Hello all,
the following query ends with a timeot:
SELECT ?istanza_di ?istanza_diLabel WHERE {
SERVICE wikibase:label { bd:serviceParam wikibase:language
"[AUTO_LANGUAGE],en". }
?istanza_di wdt:P31 wd:Q13442814.
}
LIMIT 10
Can anybody explain why ?
Thanks in advance
