> Now that we have weight-level control of whether scoring is needed or not, we
> could add a new clause type to BooleanQuery. It would behave like MUST exept
> that it would not participate in scoring.
> Why do we need it given that we already have FilteredQuery? The idea is that
> by having a single query that performs conjunctions, we could potentially
> take better decisions. It's not ready to replace FilteredQuery yet as
> FilteredQuery has handling of random-access filters that BooleanQuery
> doesn't, but it's a first step towards that direction and eventually
> FilteredQuery would just rewrite to a BooleanQuery.
> I've been calling this new clause type FILTER so far, but feel free to
> propose a better name.
