>
> FunctionMatchQuery internally has a TwoPhaseIterator using a constant
> matchCost. If it were customizable by the query, the user could control this
> ordering. I propose an optional matchCost via an overloaded constructor.
> Ideally the DoubleValues abstraction would have a matchCost but it doesn't,
> and even if it did, the user might just want real control over this at a
> query construction/parse level.
