body: <p>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.</p>
  
  <pre><code>SELECT ?item ?itemLabel WHERE {
    SERVICE wikibase:label {
      bd:serviceParam wikibase:language "en".
      ?item rdfs:label ?itemLabel.  
    }
  FILTER(CONTAINS(LCASE(?itemLabel), "keyword"))
  }
  LIMIT 1000
  </code></pre>
