Description

In LUCENE-6772, MultiCollector was modified to continue collecting against other leaf collectors that had not thrown a CollectionTerminatedException in cases where another one does. It would be nice if this behavior could be configurable. Some use-cases might actually want to early terminate all leaf collectors as soon as one signals early termination.

We could add a configurable option to the MultiCollector#wrap factory methods that allows users to specify the behavior they want.
