knnBeta

knnBeta 演算子は Hierarchical Navigable Small Worlds アルゴリズムを使用してセマンティック検索を実行します。Atlas Search の kNN クエリ サポートを使用して、選択した製品に類似するものを検索したり、画像を検索したりできます。

構文

knnBeta の構文は次のとおりです。

1{
2  $search: {
3    "index": "<index name>", // optional, defaults to "default"
4    "knnBeta": {
5      "vector": [<array-of-numbers>],
6      "path": "<field-to-search>",
7      "filter": {<filter-specification>},
8      "k": <number>,
9      "score": {<options>}
10    }
11  }
12}

オプション

フィールド
タイプ
説明
必要性
filter
ドキュメント
メタデータまたは特定の検索条件に基づいてドキュメントをフィルタリングする任意の Atlas Search 演算子。これにより、ベクトル検索の範囲を絞り込むことができます。
任意
k
数値
返される最近傍の数。精度を高めるために、返されるドキュメントの数（$limit）よりも大きい数値を指定できます。
必須
path
string
検索するためのインデックスを作成した knnVector タイプ フィールド。詳細については、「パス構築」を参照してください。
必須
score
ドキュメント
結果で一致するドキュメントに割り当てられたスコア。詳細については、「スコアリング動作」を参照してください。
任意
vector
数字の配列
クエリ ベクトルを表す BSON 型int または double の数値の配列。配列のサイズは、フィールドのインデックスで指定されたベクトル dimensions の数と一致する必要があります。
必須

動作

Atlas Search タイプ knnVector としてインデックスが作成されたフィールドに対してのみ、kNN クエリを実行できます。

$search ステージの後に $limit を使用して、knnBeta クエリ結果内のドキュメントの数を制限できます。k の値を $limit の値よりも高く設定することをお勧めします。このオーバーリクエスト パターンは、近似最近傍探索でレイテンシと再現率のトレードオフを行う主な方法です。経験的に、5 ～ 10 倍の倍率が多くのユースケースでうまく機能することがわかっていますが、特定のデータセットに合わせてこれを調整することをお勧めします。

例

次のクエリは、クエリに対して最近傍の150 個を検索し、残りの結果数を 50 に制限します。

1db.<collection>.aggregate({
2  "$search": {
3    "knnBeta": {
4      "vector": <array-of-numbers-to-search>,
5      "path": <indexed-field-to-search>,
6      "k": 150
7    }
8  }
9},
10{
11  "$limit": 50
12})

パフォーマンス

クエリのパフォーマンスを向上させるには、結果内にすべてのフィールドが必要な場合を除き、$project ステージを使用して結果の中に返すフィールドを選択します。$project ステージではベクトル フィールドを除外することをお勧めします。

スコアリング

$project ステージで $meta 式 searchScore を含む score フィールドを使用すると、結果内にドキュメントのスコアを返すことができます。

Atlas Search は、kNN クエリの結果を 0 から 1 までの固定範囲でのみスコア付けします。cosine および dotProduct 類似性については、Atlas Search は以下のアルゴリズムを使用してスコアを正規化します。

score = (1 + cosine/dot_product(v1,v2)) / 2

制限

knnBeta 演算子はクエリの最上位演算子でなければならないため、以下の中で knnBeta 演算子を使用することができません。

knnBeta 演算子を使用して、 vectorSearch タイプのインデックスを使用してインデックス付けされたフィールドをクエリすることはできません。knnBeta 演算子では$search ソート オプションは使用できません。

$search ステージ以降に $skip と $limit を使用して Atlas Search の結果をページ分割することはお勧めしません。

例

以下のクエリは、knnBeta 演算子を使用してサンプル sample_mflix.embedded_movies コレクションを検索します。クエリは、OpenAI の text-embedding-ada-002 埋め込みモデルを使用して作成された埋め込みを含む plot_embedding フィールドを検索します。サンプル コレクションを Atlas クラスターに追加し、コレクションのサンプル インデックス定義を作成した場合は、sample_mflix データベースに切り替えて、コレクションに対して次のクエリを実行できます。

以下のクエリは、knnBeta 演算子を使用して plot_embedding フィールドで vector 次元を検索し、結果から最大 5 件の最近傍を要求します。また、以下を行うため、$project ステージの指定も行います。

  • _id フィールドを除外し、結果に plot フィールドと title フィールドを含める。

  • 結果に score という名前のフィールドを追加する。

1db.embedded_movies.aggregate([
2  {
3    "$search": {
4      "index": "default",
5      "knnBeta": {
