I am confused: if I use search on the Market app on Android 2.2, it tells me often that there are hundreds or even thousands of matches, but shows exactly 10, no more. Is there a way to scroll / page / whatever that I've overlooked? 8-}
When you scroll to thr bottom of the list it should automatically load more results. Mine sometimes gets hung up and shows the "thinking" symbol for a few seconds, but then loads more.
Based on your question here, I see you're using a tablet. You may need to rotate your device to landscape mode in order for the paging in the Market to work correctly. I have to do this with my rooted Nook Color.
