I think that in BooleanQuery and related classes we mostly aggregate
child scores by summing (although there is DisjunctionMaxScorer which
doesn't exactly take the max?). I have a use case where I want to take
the min score from a bunch of required terms. To do this I had to
write a new query and fork BlockMaxConjunctionScorer. I wonder if it
would make sense to expose the aggregator to callers, perhaps with an
enum, since we can't support arbitrary functions, but we could support
at least min, max, sum?
