Hi,  
I'm trying to make an aggregation that will end when several phrases are seen, but I can't tell in advance their incoming order, and I want to wait for all of them to arrive (until a minimal timeout.)  
However, I don't want just to set a large timeout since I can wait too much time.  
I think the best way would be to dynamically set the checking inside the aggregation, something like:  
end\_of\_task =\> CheckIfShouldEndTask()  
But I think that's not going to work.

I had the same problem also with when to start the aggregation, but for that there is a solution.  
I set: map\_action =\> "create\_or\_update"  
so the aggregation begins when the earliest condition is met.  
Is there a good way to end aggregation when the latest condition is met?

Thanks.
