Let me look into it - the reason its not there right now is because the search routine doesn't actually ever know how many results its found. Basically it searches till it finds 20, then stops, then for the next page finds 20 more, starting from the last one it found on the previous page. In theory, this cuts down the amount of search time by a fairly significant (though linear) amount. Realistically, I'll try it and see what happens

Update: yeah, it looks possible. I'll make it give you a list of pages sometime this week.
