---------------------------------------
{quote}right now its too difficult to improve the implementation (and there are
massive memory inefficiencies) or even provide different options. too much
stuff tangled into one format. its so bad that we cant even name it.

I didn't intend to discuss about implementations at here but try to deal with
the naming issue, I understand the current status of the vector search (or
hnsw) is not perfect though.
It sounds like that we can not only name it but also ship it with 9.0 to me. If
so, I'm really afraid to say but the discussion seem to go beyond this issue
(and me); should we return to LUCENE-9004 or LUCENE-9322 to treat the
fundamental question.

> Main points here are 1) use plural form for consistency, and 2) use more
> specific name for ann search (second point could be optional).
> A few alternatives were proposed:
> - VectorsFormat
> - VectorValuesFormat
> - NeighborsFormat
> - DenseVectorsFormat
