Added wiki-page search for 5-2-stable, Fixed issue #4310

Created by: coverer

Since the master travis-ci build failed somehow, I applied the patch to a clean 5-2-stable and it works on our production machine.

You can now search for content in wiki pages. It gives the page, but not a snippet of the page, that may be a nice improvement for the future.
