Sounds like a subtree search using some kind of sorting of the entries
you receive. You save the entry DN of the entry with the greatest
interger attribute before getting the next one. Base DN for the subtree
search is ofcourse the parentnode DN of the subtree you wish to explore.
If you use indexing you could speed the search but you still have to go
through the whole subtree.

If this sounds interesting I could give you details about the
search(without any specific filters).
