I meant that the order quantity was over 1000, not the number of pieces of
data. I'd be quite happy with 25 returned matches

It's not bulk order processing - I was trying to find a parallel in the
example I gave for what I am trying to do.

Perhaps I have a system which has users who record what films/movies they
see and the system keeps an up-to-date list of all movies as they are
released.

What if the user wants to see a list of all the movies which came out last
month which they *haven't* seen. Is there a way to do that? I can see from
your answer before that I can limit the list to ones which the user has
added to their list of viewed films, but is it possible to get the
complimentary data set?

Thanks,

Ian
