Why only two responses for a url?

I have written a plugin to go through a directory on my pc and index
all the htm/asp pages I have, and it adds them to GDS with a uri of
http://intranet/page1.asp ...page2.asp etc.

However when I do a search, I only ever get two pages returned (one
tabbed in to show it's on the same site) how can I force GDS to return
all the matched pages and not just the first two?
