Sitelink is basically a specific kind of identifier (though not store in statements) So we may image we can search them like haswbstatement:P31=Q484170 -haswbsitelink:jawiki in order to find communes of France that is missing in jawiki.
(probably haswbsitelink:enwiki=Test should also work, but this can already be achieved via Special:ItemByTitle.)
This is not efficient at all. For example:
SELECT ?item {
?article schema:about ?item.
?article schema:inLanguage "en" .
MINUS {?item rdfs:label ?label FILTER(lang(?label)="en")}
} LIMIT 1000This query can not run
Another query that can not run:
SELECT (COUNT(distinct ?item) as ?c){
?item wdt:P1566 [].
?page schema:about ?item. ?page schema:isPartOf <https://ceb.wikipedia.org/>.
}Closing out low/est priority tasks over 6 months old with no activity within last 6 months in order to clean out the backlog of tickets we will not be addressing in the near term. Please feel free to reopen if you think a ticket is important, but bare in mind that given current priorities and resourcing, it is unlikely for the Search team to pick up these tasks for the indefinite future. We hope that the requested changes have either been addressed by or made irrelevant by work the team has done or is doing -- e.g. upgrading Elasticsearch to a newer version will solve various ES-related problems -- or will be subsumed by future work in a more generalized way.
