How can I query Wikidata to get all items that have labels contain a word? I tried this but didn\'t work; it retrieved nothing.
SELECT ?item ?itemLabel WHERE {
Following your question and the useful comments provided, I ended up with this query
SELECT ?item ?itemLabel
WHERE {
?item rdfs:label ?itemLabel.
FILTER(CONTAINS(LCASE(?itemLabel), "city"@en)).
} limit 10
For which I got those results
item itemLabel
wd:Q515 city
wd:Q7930989 city
