> This query accepts any document where any of the provided set of longs
> was indexed into the specified field as a numeric DV field
> (NumericDocValuesField or SortedNumericDocValuesField).  You can use
> it instead of DocValuesTermsQuery when you have field values that can
> be represented as longs.
> Like DocValuesTermsQuery, this is slowish in general, since it doesn't
> use an inverted data structure, but in certain cases (many
> terms/numbers and fewish matching hits) it should be faster than using
> TermsQuery because it's done as a "post filter" when other (faster)
> query clauses are MUST'd with it.
> In such cases it should also be faster than DocValuesTermsQuery since
> it skips having to resolve terms -> ords.
