IndexType

Addedv2.6.x

Enumerates the supported index algorithms for vector and scalar fields.

type IndexType string

VALUES:

AUTOINDEX = "AUTOINDEX"

Automatically selects the best index type.
Trie = "Trie"

Trie index for string fields.
Sorted = "STL_SORT"

Sorted index for scalar fields.
Inverted = "INVERTED"

Inverted index for scalar fields.
BITMAP = "BITMAP"

Bitmap index for low-cardinality scalar fields.
RTREE = "RTREE"

R-tree index for spatial data.

Example

import (
    "context"

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

ctx, cancel := context.WithCancel(context.Background())
defer cancel()

milvusAddr := "YOUR_CLUSTER_ENDPOINT"

cli, err := milvusclient.New(ctx, &milvusclient.ClientConfig{
    Address: milvusAddr,
})
if err != nil {
    // handle error
}

defer cli.Close(ctx)

// Create an HNSW index on a float vector field
hnswIndex := index.NewHNSWIndex(index.MetricTypeL2, 16, 200)
_, err = cli.CreateIndex(ctx, milvusclient.NewCreateIndexOption(
    "my_collection", "embedding", hnswIndex))
if err != nil {
    // handle error
}

// Create an IVF_FLAT index
ivfIndex := index.NewIvfFlatIndex(index.MetricTypeL2, 128)
_, err = cli.CreateIndex(ctx, milvusclient.NewCreateIndexOption(
    "my_collection", "embedding2", ivfIndex))
if err != nil {
    // handle error
}
