Method Summary

Modifier and Type Method and Description
static RescoringOptions fromJson(JsonReader jsonReader)

Reads an instance of RescoringOptions from the JsonReader.
Double getDefaultOversampling()

Get the defaultOversampling property: Default oversampling factor.
VectorSearchCompressionRescoreStorageMethod getRescoreStorageMethod()

Get the rescoreStorageMethod property: Controls the storage method for original vectors.

Constructor Details

RescoringOptions

public RescoringOptions()

Creates an instance of RescoringOptions class.

Method Details

fromJson

public static RescoringOptions fromJson(JsonReader jsonReader)

Reads an instance of RescoringOptions from the JsonReader.

Parameters:

jsonReader - The JsonReader being read.

Returns:

An instance of RescoringOptions if the JsonReader was pointing to an instance of it, or null if it was pointing to JSON null.

Throws:

IOException

 - If an error occurs while reading the RescoringOptions.

getDefaultOversampling

public Double getDefaultOversampling()

Get the defaultOversampling property: Default oversampling factor. Oversampling retrieves a greater set of potential documents to offset the resolution loss due to quantization. This increases the set of results that will be rescored on full-precision vectors. Minimum value is 1, meaning no oversampling (1x). This parameter can only be set when 'enableRescoring' is true. Higher values improve recall at the expense of latency.

Returns:

the defaultOversampling value.

getRescoreStorageMethod

public VectorSearchCompressionRescoreStorageMethod getRescoreStorageMethod()

Get the rescoreStorageMethod property: Controls the storage method for original vectors. This setting is immutable.

Returns:

the rescoreStorageMethod value.

isEnableRescoring

public Boolean isEnableRescoring()

Get the enableRescoring property: If set to true, after the initial search on the compressed vectors, the similarity scores are recalculated using the full-precision vectors. This will improve recall at the expense of latency.

Returns:

the enableRescoring value.

setDefaultOversampling

public RescoringOptions setDefaultOversampling(Double defaultOversampling)

Set the defaultOversampling property: Default oversampling factor. Oversampling retrieves a greater set of potential documents to offset the resolution loss due to quantization. This increases the set of results that will be rescored on full-precision vectors. Minimum value is 1, meaning no oversampling (1x). This parameter can only be set when 'enableRescoring' is true. Higher values improve recall at the expense of latency.

Parameters:

defaultOversampling - the defaultOversampling value to set.

Returns:

the RescoringOptions object itself.

setEnableRescoring

public RescoringOptions setEnableRescoring(Boolean enableRescoring)

Set the enableRescoring property: If set to true, after the initial search on the compressed vectors, the similarity scores are recalculated using the full-precision vectors. This will improve recall at the expense of latency.

Parameters:

enableRescoring - the enableRescoring value to set.

Returns:

the RescoringOptions object itself.

setRescoreStorageMethod

public RescoringOptions setRescoreStorageMethod(VectorSearchCompressionRescoreStorageMethod rescoreStorageMethod)

Set the rescoreStorageMethod property: Controls the storage method for original vectors. This setting is immutable.

Parameters:

rescoreStorageMethod - the rescoreStorageMethod value to set.

Returns:

the RescoringOptions object itself.

toJson

public JsonWriter toJson(JsonWriter jsonWriter)

Parameters:

jsonWriter

Throws:
