Feature summary (what you would like to be able to do and where):
Have a special page listing the search queries entered on the wiki.

Use case(s) (list the steps that you performed to discover that problem, and describe the actual underlying problem which you want to solve. Do not describe only a solution):
I can't see what my wiki users are searching for. If I could this might give me me an idea of the topics that would be of interest to wiki readers. Analytics doesn't show this either. I don't know of any extension that enables this.

Benefits (why should this be implemented?):
This would help wiki managers to find out what articles users find most useful or ones that should be added to the wiki.
