I just installed CirrusSearch on my knowledge base wiki and it's working mostly as intended. I have no problems with my documents in the main namespace (where I put mostly infrastructure pages like teams, services, etc.). However, all my actual knowledge base articles reside in a second namespace (named KB), have a pagename containing of numbers which are randomly generated. The actual displayed title is set via {{DISPLAYTITLE:Nice Title}}.
The KB namespace is searched correctly and the results are displayed as intended. What is rather anoying is that the search suggestion works only on the actual page title (that is something like KB:1234567). Is there a way, I can have the suggestor use and display the display title for a) that namespace or b) all namespaces?
