前回の記事 ではベクトル距離を用いた検索に絞って機能を紹介しましたが、その後、多くの記事で、ベクトルを使った RAG の実装方法がより包括的に紹介されています。
検索の度にベクトル距離を計算して比較しようとすると、ベクトルの数（RAG であれば検索対象の文書から作成されたチャンクの数）やベクトルの次元数に応じて、計算負荷が高くなってしまいます。
そこで、多くのベクトル・データベースは、索引を用いて「近似した」近傍検索を実装しています。Oracle Database 23ai にもそのようなベクトル索引が追加されているため、この記事の前半では使い方を見ておき、後半では近傍検索の高速化を体験してみましょう！
ベクトル索引が使用された際の実行計画

メモリ領域の確保
Oracle Database 23ai は一般的に使われている 2 つのベクトル索引である、Hierarchical Navigable Small World (HNSW) 索引と Inverted File Flat (IVF) 索引を搭載しています。ここでは、特に高速で高精度とされている HNSW 索引を試します。
HNSW 索引はメモリを多く消費するので、Oracle Database 23ai ではメモリ内に ベクトル・プール と呼ばれる領域を確保することで、この索引が利用可能になります。
CDB の初期化パラメータにサイズを設定します。
ALTER SYSTEM SET vector_memory_size=300M SCOPE=SPFILE;
このパラメータの変更には再起動が必要です。
shutdown immediate
startup
設定されたことを確認します。
show parameter vector_memory_size
NAME TYPE VALUE
------------------ ----------- -----
vector_memory_size big integer 304M
ベクトル索引の作成
前回の記事で作成している GALAXIES 表 の ENBEDDING 列（VECTOR 型）に対して HNSW 索引を作成します。この際には、ベクトル間の距離の計算方法を指定しておく必要があるため、ここでは COSINE（コサイン距離）とします。この場合、VECTOR_DISTANCE 関数を使って近傍検索を実行する際には、COSINE が指定されたときのみこの索引が使用されます。
CREATE VECTOR INDEX galaxies_hnsw_idx ON galaxies (embedding)
ORGANIZATION INMEMORY NEIGHBOR GRAPH DISTANCE COSINE;
ベクトル索引の詳細は以下のドキュメントを参照してください。
索引を使わない「完全な」近傍検索
まず、前回紹介した VECTOR_DISTANCE 関数を用いて、銀河「M31」のベクトルにコサイン距離が近いものを 3 つ取得します。
SELECT name
FROM galaxies
ORDER BY VECTOR_DISTANCE(embedding, '[0.26833928, 0.012467232, -0.48890606, 0.61341953, 0.5590402]', COSINE)
FETCH FIRST 3 ROWS ONLY;
NAME
--------------------------------------------------
M31
M77
M91
実行計画を見てみると、索引は使われておらず、表がフルスキャンされていることがわかります。全ての行（ここでは 9 つの銀河）のベクトルと与えたベクトルの間のコサイン距離を計算して、これをソートしていると考えられます。
EXPLAIN PLAN FOR
SELECT name
FROM galaxies
ORDER BY VECTOR_DISTANCE(embedding, '[0.26833928, 0.012467232, -0.48890606, 0.61341953, 0.5590402]', COSINE)
FETCH FIRST 3 ROWS ONLY;
SELECT * FROM TABLE(DBMS_XPLAN.DISPLAY);
------------------------------------------------------------------------------------

| 4 | TABLE ACCESS FULL | GALAXIES | 9 | 657 | 3 (0)| 00:00:01 |
------------------------------------------------------------------------------------
索引を使って「近似された」近傍検索
次に、FETCH 句に APPROX（approximate = 近似する）というキーワードを追加して、近似された近傍検索の結果を取得します。結果は同じ 3 つの銀河が返されています。
SELECT name
FROM galaxies
ORDER BY VECTOR_DISTANCE(embedding, '[0.26833928, 0.012467232, -0.48890606, 0.61341953, 0.5590402]', COSINE)
FETCH APPROX FIRST 3 ROWS ONLY;
NAME
--------------------------------------------------
M31
M77
M91
実行計画を見てみると、今回は索引が使用されていて、GALAXIES 表の 3 行のみにアクセスしていることがわかります。
EXPLAIN PLAN FOR
SELECT name
FROM galaxies
ORDER BY VECTOR_DISTANCE(embedding, '[0.26833928, 0.012467232, -0.48890606, 0.61341953, 0.5590402]', COSINE)

----------------------------------------------------------------------------------------------------
このように、近傍検索にベクトル索引が利用されることがわかりました。
大きめのデータで実験 （準備）
上のサンプルではデータサイズが小さいため、ベクトル索引による性能向上を感じることができません。そこで、ランダムに抽出した日本語 Wikipedia の文書を用いて、以下のようなデータを作成して実験してみました。
- 検索対象の wiki_ja_10k_embedding 表
- 元の Wikipedia 文書の数：10,000
- 切り出したチャンクの数：25,050（＝表の行数）
- ベクトルの次元数：1,536
- クエリ
- 質問「日本の離島について教えて下さい」のベクトル表現
- ベクトルの次元数：1,536
この実験は、前回の記事 で用いた Oracle Database 23ai の無償版 Docker イメージで再現できるので、興味のある方は試してみてください。
sys でログインして myuser にディレクトリ作成の権限を与えます。
sys
GRANT create any directory, drop any directory TO myuser;
OS 上でディレクトリ（ここでは /dir01）を作成した後、myuser でデータベース上のディレクトリを作成します。
myuser
CREATE DIRECTORY dir01 AS '/dir01';
wiki_ja_10k_embedding 表のダンプをダウンロードします。
cd /dir01
curl -O https://objectstorage.ap-tokyo-1.oraclecloud.com/n/nr92jg8wdcil/b/public/o/wiki_ja_10k_embedding.dmp
wiki_ja_10k_embedding 表をインポートします。
impdp myuser/password123@freepdb1 \
tables=myuser.wiki_ja_10k_embedding directory=dir01 dumpfile=wiki_ja_10k_embedding.dmp logfile=wiki_ja_10k_embedding.log
大きめのデータで実験 （結果）
さて、検索対象の表が用意できたので、早速クエリを実行してみましょう。
クエリ結果を日本語で表示したいので、環境変数を設定してから myuser でログインします。
export NLS_LANG=JAPANESE_JAPAN.UTF8
sqlplus myuser/password123@freepdb1
はじめに、完全近傍検索を実行します。「日本の離島について教えて下さい」という質問が、1,536 次元という大きなベクトルになっているので、これをクエリに含めるために、いくつかに分割して TO_CLOB 関数を使いながら再度結合する、といったことをしています。実際のアプリケーションではベクトル型のバインド変数が使われます。
今回は FETCH 句に EXACT を指定しています。このキーワードは有無に関わらず（ベクトル索引がない場合には APPROX が指定されていても）完全近傍検索が実行されますが、このように明示的に指定しておいてもわかりやすいです。

今回の場合、結果は完全近傍検索と一致していますが、近似近傍検索の結果は異なる場合もあります。その精度を許容できる場合には、ベクトル索引により大きな性能向上を得られることがわかりました。検索対象のデータ量がさらに多くなっていったときには、近似近傍検索が不可欠となることが想像できます。
上記で使用した wiki_ja_10k_embedding 表の作成過程や LangChain を使ったベクトル索引の使い方は こちらの記事 で説明しているので、詳しく知りたい方はぜひご参照ください。
