So while Swarm Intelligence is online, casting Knowledge exploitation will give you two of it, then you search opp`s library, find a piece and you don`t copy it, you may PLAY it, so if you choose to play, you make it double too, right? In the end you get 4 opp`s spells, right? Right?
Swarm Intelligence's ability will trigger whenever you cast an instant or sorcery spell, including a card you cast due to Knowledge Exploitation. (Note that Knowledge Exploitation's Oracle text now says "You may cast that card..." rather than "You may play that card..." [C.R. 108.1]; cards no longer speak of "playing" an instant or sorcery card; see also this thread.)
