Right now, wikidata completion search box only searches entity namespaces. We may want to be able to search titles in article namespaces too, e.g. when searching for Wikidata:Project chat we may want to display both entity with label "Wikidata:Project chat" and the actual page having this title.
Current proposal for implementing this is:
- Refactor GUI code so that instead of Wikidata fully replacing completion search box, the standard box allows augmenting the result set data and display
- Make the GUI code for standard implementation call standard title search, and in addition Wikidata part of the code calls wbsearchentities, as now
- Display both sets of results (likely wbsearchentities first, title search second)
