you consider it's having to match item-by-item in two very large and

just return a figure for matching articles, rather than a list, when
you expect it to be unusually large?
It's still going to have to calculate the intersection of the two sets (the
computationally and IO intensive task) in order to then calculate the size of said
intersection.
