quantizeScore

public long quantizeScore(byte[] q)
                   throws IOException

Description copied from class: ES940OSQVectorsScorer

compute the quantize distance between the provided quantized query and the quantized vector that is read from the wrapped IndexInput.

Overrides:

quantizeScore in class ES940OSQVectorsScorer

Throws:

IOException

quantizeScoreBulk

public void quantizeScoreBulk(byte[] q,
 int count,
 float[] scores)
                       throws IOException

Description copied from class: ES940OSQVectorsScorer

Compute the quantize distance between the provided quantized query and the quantized vectors that are read from the wrapped IndexInput. The number of quantized vectors to read is determined by and the results are stored in the provided array.

Overrides:

quantizeScoreBulk in class ES940OSQVectorsScorer

Throws:

IOException

quantizeScoreBulkOffsets

public void quantizeScoreBulkOffsets(byte[] q,
 int[] offsets,

 float[] scores,
 int count)
                              throws IOException

Description copied from class: ES940OSQVectorsScorer

Compute the quantize distance between the provided quantized query and the quantized vectors that are read from the wrapped IndexInput. The number of quantized vectors to read is determined by and the results are stored in the provided array. Only the vectors that are indexed in the provided are scored; the others are skipped.

Overrides:

                throws IOException

Description copied from class: ES940OSQVectorsScorer

Bulk score overload; same as ES940OSQVectorsScorer.scoreBulk(byte[], float, float, int, float, VectorSimilarityFunction, float, float[], int) with ES940OSQVectorsScorer.bulkSize as the default bulkSize param value.

Overrides:

Throws:

IOException

scoreBulk

public float scoreBulk(byte[] q,
 float queryLowerInterval,
 float queryUpperInterval,
 int queryComponentSum,
 float queryAdditionalCorrection,
 org.apache.lucene.index.VectorSimilarityFunction similarityFunction,
 float centroidDp,
 float[] scores,
 int bulkSize)
                throws IOException

Description copied from class: ES940OSQVectorsScorer

Compute the distance between the provided quantized query and the quantized vectors that are read from the wrapped IndexInput.

The number of vectors to score is defined by . The expected format of the input is as follows: First the quantized vectors are read from the input,then all the lower intervals as floats, then all the upper intervals as floats, then all the target component sums as shorts, and finally all the additional corrections as floats.

The results are stored in the provided array.

Overrides:

scoreBulk in class ES940OSQVectorsScorer

Throws:

IOException

 int count)
                       throws IOException

Description copied from class: ES940OSQVectorsScorer

Compute the distance between the provided quantized query and the quantized vectors that are read from the wrapped IndexInput.

Similar to ES940OSQVectorsScorer.scoreBulk(byte[], float, float, int, float, org.apache.lucene.index.VectorSimilarityFunction, float, float[]), but only the vectors indexed by the provided are scored; the others are skipped.

The results are stored in the provided array.
