Review Comment:
> @msokolov I suppose that is ok for folks that understand the depths of
codec formats. But we are seriously complicating somebody's life that wants to
use kNN and scalar quantized flat codec. Now they cannot use the knn query, but
instead have to use some specialized query they come up with themselves.

> I think we at least should have a "flat vector query"? or something?
Something that always does exact search so that typical users don't have to do
this iterating & casting stuff?
Rather than having a new query can we just reuse the old query where for a
field we get the right KNNVectorsReader and hit the search interface of the
reader that does the exact search or HNSW based search based on whatever
implementation the KNNVectorsReader have used.
