> DrillDown is a helper class which the user can use to convert a facet value that a user
selected into a Query for performing drill-down or narrowing the results. The API has several
static methods that create e.g. a Term or Query.
> Rather than creating a Query, it would make more sense to create a Filter I think. In
most cases, the clicked facets should not affect the scoring of documents. Anyway, even if
it turns out that it must return a Query (which I doubt), we should at least modify the impl
to return a ConstantScoreQuery.
