Go

func NewHNSWAnnParam(ef int) hsnwAnnParam

Go

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

)

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

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