When searching on Special:Search, a suggestion is given to create a new page with the given search term if an exact match is not found. e.g. 'Create the page "Berlin" on this wiki!' https://test.wikidata.org/w/index.php?title=Special:Search&profile=default&search=Prague&fulltext=Search&uselang=es It is possible to disable this via a hook it items are in the main namespace. On Wikidata (in some languages), the message is set to an empty message so nothing appears.
