Returns the ByteVectorValues for the given field. The behavior is undefined if the given field doesn't have KNN vectors enabled on its FieldInfo. The return value is never null.

getFloatVectorValues

open override fun getFloatVectorValues(field: String): FloatVectorValues?

Returns the FloatVectorValues for the given field. The behavior is undefined if the given field doesn't have KNN vectors enabled on its FieldInfo. The return value is never null.

getGraph

open override fun getGraph(field: String): HnswGraph

Return the stored HnswGraph for the given field.

getQuantizationState

open override fun getQuantizationState(field: String): ScalarQuantizer?

getQuantizedVectorValues

open override fun getQuantizedVectorValues(field: String): QuantizedByteVectorValues?

ramBytesUsed

open override fun ramBytesUsed(): Long

Return the memory usage of this object in bytes. Negative values are illegal.

open override fun search(field: String, target: ByteArray, knnCollector: KnnCollector, acceptDocs: Bits?)

open override fun search(field: String, target: FloatArray, knnCollector: KnnCollector, acceptDocs: Bits?)

Return the k nearest neighbor documents as determined by comparison of their vector values for this field, to the given vector, by the field's similarity function. The score of each document is derived from the vector similarity in a way that ensures scores are positive and that a larger score corresponds to a higher ranking.
