I'm running into this problem too. Queries are slow or even time out for
chemicals. The hints to do not seem to improve the query time significantly:
SELECT ?wikis ?compound WHERE {
?compound wdt:P31 wd:Q11173 ;
wikibase:sitelinks ?wikis . hint:Prior hint:rangeSafe true .
FILTER(NOT EXISTS {?compound wdt:P2119 []})
} ORDER BY DESC(?wikis)
LIMIT 100
