You can write your own function which can use searchpos() function,
setting mark with ':normal mmgg' (or even better remember the position in
a global (g:) variable. You can set the nowrapscan flag on the search()
function and only thet if the position is beyond (for forward search) if
it already hit bottom. Finally, you can write a command which invokes
the function. If you use <q-args> you will type a pattern in exactly
the same way as you type it in the command line. The last step would be
to makes maps n and N which invokes the search, but in such a way that
it uses the starting position set by the first search. I guess this
difficulty is the reason why vim behaves like it behaves. How you could
now using n/N that the search is a new search.

AFAIK vim has no option for that.

Happy Vimming,
