快速入門：使用 REST 進行向量搜尋
瞭解如何使用 搜尋 REST API 在 Azure AI 搜尋服務中建立、載入和查詢向量。
在 Azure AI 搜尋服務中，「向量存放區」具有定義向量和非向量欄位的索引結構描述、建立內嵌空間的演算法向量設定，以及向量欄位定義上用於查詢要求的設定。 建立索引 API 會建立向量存放區。
如尚未擁有 Azure 訂用帳戶，請在開始之前先建立免費帳戶。
注意
穩定的 2023-11-01 REST API 版本取決於數據區塊化和內嵌的外部解決方案。 如果您想要評估內建的數據區塊化和向量化功能 （公開預覽） 功能，請嘗試匯入和向量化數據精靈，以取得端對端逐步解說。
必要條件
具有 REST 用戶端的 Visual Studio Code。 如果您需要開始使用的協助，請參閱 快速入門：使用 REST 進行文字搜尋。
Azure AI 搜尋，在任何區域和任何層級。 您可以針對本快速入門使用免費層，但建議針對較大的數據檔使用基本或更高層級。 在您的 目前訂用帳戶下建立或 尋找現有的 Azure AI 搜尋資源 。
大部分現有的服務都支援向量搜尋。 對於在 2019 年 1 月之前建立的一小部分服務，包含向量欄位的索引在建立時會失敗。 在此情況下，必須建立新的服務。
選擇性地，具有 部署的
text-embedding-ada-002Azure OpenAI 資源。 來源.rest檔案包含產生新文字內嵌的選擇性步驟，但我們提供預先產生的內嵌，以便省略此相依性。
下載檔案
從 GitHub 下載 REST 範例 ，以在此快速入門中傳送要求。 如需詳細資訊，請參閱 從 GitHub 下載檔案。
您也可以在本機系統上啟動新的檔案，並使用本文中的指示手動建立要求。
複製搜尋服務金鑰和 URL
REST 呼叫需要每個要求的搜尋服務端點和 API 金鑰。 您可以從 Azure 入口網站 取得這些值。
登入 Azure 入口網站。 移至 [ 概觀] 頁面並複製 URL。 範例端點看起來會像是
https://mydemo.search.windows.net。選取 [設定> Keys]，然後複製管理密鑰。 管理員 索引鍵可用來新增、修改和刪除物件。 有兩個可交換的系統管理密鑰。 複製任一個。
建立向量索引
建立索引 （REST） 會建立向量索引，並在您的搜尋服務上設定實體數據結構。
索引架構是圍繞酒店內容進行組織。 範例數據是由向量和非向量名稱和七家虛構旅館的描述所組成。 此架構包含向量索引編製和查詢的組態，以及語意排名的組態。
在 Visual Studio Code 中開啟新的文字檔。
將變數設定為您稍早收集的搜尋端點和 API 金鑰。
@baseUrl = PUT-YOUR-SEARCH-SERVICE-URL-HERE @apiKey = PUT-YOUR-ADMIN-API-KEY-HERE以擴展名儲存
.rest盤案。貼上下列範例，以在搜尋服務上建立
hotels-vector-quickstart索引。### Create a new index POST {{baseUrl}}/indexes?api-version=2023-11-01 HTTP/1.1 Content-Type: application/json api-key: {{apiKey}} { "name": "hotels-vector-quickstart", "fields": [ { "name": "HotelId", "type": "Edm.String", "searchable": false, "filterable": true, "retrievable": true, "sortable": false, "facetable": false, "key": true }, { "name": "HotelName", "type": "Edm.String", "searchable": true, "filterable": false, "retrievable": true, "sortable": true, "facetable": false }, { "name": "HotelNameVector", "type": "Collection(Edm.Single)", "searchable": true, "retrievable": true, "dimensions": 1536, "vectorSearchProfile": "my-vector-profile" }, { "name": "Description", "type": "Edm.String", "searchable": true, "filterable": false, "retrievable": true, "sortable": false, "facetable": false }, { "name": "DescriptionVector", "type": "Collection(Edm.Single)", "searchable": true, "retrievable": true, "dimensions": 1536, "vectorSearchProfile": "my-vector-profile" }, { "name": "Category", "type": "Edm.String", "searchable": true, "filterable": true, "retrievable": true, "sortable": true, "facetable": true }, { "name": "Tags", "type": "Collection(Edm.String)", "searchable": true, "filterable": true, "retrievable": true, "sortable": false, "facetable": true }, { "name": "Address", "type": "Edm.ComplexType", "fields": [ { "name": "City", "type": "Edm.String", "searchable": true, "filterable": true, "retrievable": true, "sortable": true, "facetable": true }, { "name": "StateProvince", "type": "Edm.String", "searchable": true, "filterable": true, "retrievable": true, "sortable": true, "facetable": true } ] }, { "name": "Location", "type": "Edm.GeographyPoint", "searchable": false, "filterable": true, "retrievable": true, "sortable": true, "facetable": false } ], "vectorSearch": { "algorithms": [ { "name": "my-hnsw-vector-config-1", "kind": "hnsw", "hnswParameters": { "m": 4, "efConstruction": 400, "efSearch": 500, "metric": "cosine" } }, { "name": "my-hnsw-vector-config-2", "kind": "hnsw", "hnswParameters": { "m": 4, "metric": "euclidean" } }, { "name": "my-eknn-vector-config", "kind": "exhaustiveKnn", "exhaustiveKnnParameters": { "metric": "cosine" } } ], "profiles": [ { "name": "my-vector-profile", "algorithm": "my-hnsw-vector-config-1" } ] }, "semantic": { "configurations": [ { "name": "my-semantic-config", "prioritizedFields": { "titleField": { "fieldName": "HotelName" }, "prioritizedContentFields": [ { "fieldName": "Description" } ], "prioritizedKeywordsFields": [ { "fieldName": "Tags" } ] } } ] } }選取 [傳送要求]。 回想一下，您需要 REST 用戶端傳送要求。 您應該會有
HTTP/1.1 201 Created回應。 回應主體應該包含索引架構的 JSON 表示法。重點︰
- 集合
fields包含文字和向量搜尋所需的索引鍵欄位和文字和向量字段（例如Description和DescriptionVector）。 在同一個索引中共置向量和非向量字段可啟用混合式查詢。 例如，您可以將篩選、文字搜尋與語意排名和向量結合成單一查詢作業。 - 向量欄位必須是
type: Collection(Edm.Single)和dimensionsvectorSearchProfile屬性。 - 區
vectorSearch段是近似鄰近演算法組態和配置檔的陣列。 支持的演算法包括階層式導覽小型世界和詳盡的 K 近鄰。 如需詳細資訊，請參閱 向量搜尋中的相關性評分。 - [選擇性]：組
semantic態可重新建立搜尋結果。 您可以針對組態中所指定的字串字段，重新進行類型semantic查詢的結果。 若要深入瞭解，請參閱 語意排名概觀。
- 集合
上傳文件
建立和載入索引是個別的步驟。 在 Azure AI 搜尋中，索引包含搜尋服務上執行的所有可搜尋數據和查詢。 針對 REST 呼叫，數據會以 JSON 檔的形式提供。 針對這項工作使用 Documents- Index REST API 。
URI 會擴充以包含 docs 集合和 index 作業。
重要
下列範例無法執行程序代碼。 為了可讀性，我們排除了向量值，因為每個值都包含 1,536 個內嵌，這對於本文而言太長。 如果您想要嘗試此步驟，請從 GitHub 上的範例複製可執行的程式碼。

重點︰
- 承載中的檔是由索引架構中定義的欄位所組成。
- 向量欄位包含浮點值。 維度屬性的最小值為 2，且每個浮點數上限為 3,072。 本快速入門會將 dimensions 屬性設定為 1,536，因為這是 Open AI 文字 內嵌-ada-002 模型所產生的內嵌大小。
執行查詢
現在已載入檔，您可以使用檔 - 搜尋貼文 （REST） 來對其發出向量查詢。
有數個查詢可示範各種模式：
本節中的向量查詢是以兩個字串為基礎：
- 搜尋字串：
historic hotel walk to restaurants and shopping - 向量查詢字串 （向量化為數學表示法）：
classic lodging near running trails, eateries, retail
向量查詢字串在語意上類似於搜尋字串，但它包含搜尋索引中不存在的詞彙。 如果您對 classic lodging near running trails, eateries, retail執行關鍵詞搜尋，則結果為零。 我們使用此範例示範如何取得相關結果，即使沒有相符的字詞也一樣。
重要
下列範例無法執行程序代碼。 為了可讀性，我們排除了向量值，因為每個數位都包含 1,536 個內嵌，對於本文而言太長。 如果您想要嘗試這些查詢，請從 GitHub 上的範例複製可執行的程式代碼。
單一向量搜尋
貼上POST要求以查詢搜尋索引。 然後選取 [ 傳送要求]。 URI 會擴充以包含
/docs/search運算符。### Run a query POST {{baseUrl}}/indexes/hotels-vector-quickstart/docs/search?api-version=2023-11-01 HTTP/1.1 Content-Type: application/json api-key: {{apiKey}} { "count": true, "select": "HotelId, HotelName, Description, Category", "vectorQueries": [ { "vector"": [0.01944167, 0.0040178085 . . .

vectorQueries.vector包含查詢輸入的向量化文字、fields決定要搜尋的向量字段，並k指定要傳回的近鄰數目。向量查詢字串是

使用篩選的單一向量搜尋
您可以新增篩選，但篩選條件會套用至索引中的非函式內容。 在此範例中，篩選會套用至 Tags 字段，以篩選出任何不提供免費Wi-Fi的酒店。
貼上POST要求以查詢搜尋索引。

混合式搜尋
混合式搜尋是由單一搜尋要求中的關鍵詞查詢和向量查詢所組成。 此範例會同時執行向量查詢和全文搜索：
- 搜尋字串：
