What happens when you search, using the CompassSearchHelper, and you search past the last page?
As it stands, I have an application which searches in groups of 10, and for results where there are only (for example) 2 pages (10 on the first, 0 < x < 10 on the second), clicking "next" again will send me to pages seemingly random results, despite the fact that for a page size of 10, there are no results (or shouldn't be) past page 2. If that makes any sense? Lemme know if I need to clarify more.
