> When retrieving a Matches object from a multi-term query, such as an AutomatonQuery or TermInSetQuery, we currently find all matching term iterators up-front, to return a disjunction over all of them. This can be inefficient if we're only interested in finding out if anything matched, and are iterating over a different field to retrieve offsets.
> We can improve this by returning immediately when the first matching term is found, and only collecting other matching terms when we start iterating.
