[Wikidata-tech] Query Deadline is Expired error when Querying Wikidata

Hi,

I'm trying to find Wikidata items based on label as follows:

SELECT ?item ?itemLabel WHERE { ?item rdfs:label ?itemLabel FILTER(CONTAINS(LCASE(?itemLabel),"*keyword*")). } limit 3

However, for some cases, the following error returns n some cases Query deadline is expired. I mean it works well for some words but fails with others. Could anyone help please?
