Hi @romseygeek, I've created a changelog YAML for you. |

Our SortedBinaryDocValues class doesn't extend DocIdSetIterator, but I don't think it would be much work to make it do so and we could then get a speedup for that case too. |

Hmpf, it appears that Ordinals don't implement docId() either, so this will need to be restricted to just numerics. |

I've updated this to pull doc values directly for the fields, rather than trying to re-use FieldData. |

Rather than doing a two-phase iterator dance with advanceExact, we can use the fact that doc values iterators all extend DocIdSetIterator and reuse DocIdSetIteratorScorerSupplier if we know there are no multi-valued fields in a segment. We can also automatically rewrite to a MatchAllDocsQuery if the input FieldData is a constant value.
