If your iTunes U site is included in the iTunes Store directory you can create a link within your site to an iTunes Power Search of your site’s content.
To define the power search and create a link within your iTunes U site:
Click Power Search in the Quick Links box within iTunes U in the iTunes Store.
Choose iTunes U from the Power Search pop-up menu in the Search Results window.
Type your institution name in the Institution search field. The institution name you enter should match the “Site display name” specified in your Edit Site Settings page. If these do not match, iTunes U uses your site domain name.
Click Search or press the Enter key.
Drag the Search Results bar at the bottom of the iTunes Store window to an open plain text file. For example:
http://ax.search.itunes.apple.com/WebObjects/MZSearch.woa/wa/advancedSearch?institutionTerm=Cupertino%20University&media=iTunesU
Copy and paste the URL from step 5 into a new link in a Links box within your iTunes U site.
