Uh, no. Not using recursive search doesn't mean you have write the search
function a hundred times all over again!

Try looking at examples of recursive vs nonrecursive quicksort on the web
if you don't understand how that can be done.

DTS was designed to work with a nonrecursive search because it allows making
splitpoints when needed higher up in the tree than the point where you are
at the moment you notice you need to split.
