NewSCANNAnnParam()

This function creates an ANN search parameter set for SCANN index with configurable nprobe and reorder_k values.

Go

func NewSCANNAnnParam(nprobe int, reorderK int) scannAnnParam

PARAMETERS:

• nprobe (int)

  The number of clusters to search. Higher values improve recall but increase latency.

• reorderK (int)

  The number of candidates to reorder using the original vectors. Must be >= topK.

RETURNS:

AnnParam

An ANN search parameter instance. Pass this to a search option via WithAnnParam().

Example

Go

import (
	"github.com/milvus-io/milvus/client/v2/index"
	"github.com/milvus-io/milvus/client/v2/milvusclient"
)

// Create ANN search parameters
param := index.NewSCANNAnnParam(10, 10)

// Use with a search option
option := milvusclient.NewSearchOption("collection_name", limit, vectors).
    WithAnnParam(param)
