It took me awhile to really want to explore Rollyo. I had trouble coming up with a reason to limit a search to selected web sites. I'm just afraid I would miss a good site if my search is limited. I finally decided to create a poetry search using Rollyo. It was easy to create a search but not easy to link my search to this blog. I'll have to try again at a later date as I'm already 1 or 2 weeks behind.
The best thing about using Rollyo with students is that Wikipedia could be excluded from their searches!
Another search engine that I love is http://www.clusty.com/. The search results are clustered into categories and it really helps to focus a search.
