This is an interesting way to find supplemental results in Google and this may not be around for long.  Put this into your search query into Google and replace with your domain instead of MySite.com.  site:http://www.mysite.com/& 

The supplemental index is where Google puts pages that have low PageRank (the real kind) or ones that don’t change very often. These pages generally don’t show up in the search results unless there are not enough relevant pages in the main results to show.
