Wiki search function doesn't work as aspected

[optitsolutions]

There is a search field in the header of the wiki home page.
The search only finds terms from page titles, but not from the wiki content.
However, the global Humhub search also finds content from wiki pages.
Can the wiki search be customised for all wiki content?

@luke- I think we can close this issue now, as it works well with the new search engine.
