All Implemented Interfaces:

org.apache.lucene.util.hnsw.RandomVectorScorerSupplier

public final class Int4VectorScorerSupplier
extends Object
implements org.apache.lucene.util.hnsw.RandomVectorScorerSupplier

Int4 packed-nibble scorer supplier. Each stored vector is dims/2 packed bytes (two 4-bit values per byte), followed by corrective terms (3 floats + 1 int). The query is unpacked to dims bytes before scoring.
