It looks like the openrefine-wikibase reconciliation service uses the wbsearchentities API to find items. As far as I’m aware, the default SQL-based Wikibase search also searches other languages, but still, I think the most likely reason you’re getting different results is that Wikidata uses WikibaseCirrusSearch <https://www.mediawiki.org/wiki/Extension:WikibaseCirrusSearch>, and I assume your wiki doesn’t. If you use entity search on your wiki directly (i. e. not via Special:Search, but in suggestion boxes), does cross-language search work as it should or does it have the same problem?
