Visio search does not work

I have Visio Professional 2013 and the stencil search does not work.

If I type in an item, for example "server", it gives me the following message:

"Visio cannot provide fast search results because Windows Search is not running or is not configured properly for Visio. Please contact your system administrator."

I have an assignment due tomorrow.  Any help on this matter would be great.  Thanks--Rian
