Apply same process to different example sets

hi,

I want to apply the same process to multiple different example sets, e.g. one exampleSet after another in kind of a batch or loop process over all different example Sets, is that anyhow possible?

and in the same way, I want to collect the results separately for each different example Set, in such a way, that one result from one process run is not being overwritten from the second run (from second example set) etc.... 

do I have to do it with the Collection operator only? so that I have a result for each exampleSet in a collection maybe, and if so how do I collect the results so?
