java.lang.Object
org.apache.lucene.search.DocIdSetIterator
org.apache.lucene.index.FloatVectorValues
org.elasticsearch.index.mapper.vectors.DenormalizedCosineFloatVectorValues
public class DenormalizedCosineFloatVectorValues extends org.apache.lucene.index.FloatVectorValues
Provides the denormalized vectors. Float vectors stored with cosine similarity are normalized by default. So when reading the value for scripts, we to denormalize them.
