快速入门:使用 REST 进行矢量搜索

了解如何使用搜索 REST API 在 Azure AI 搜索中创建、加载和查询矢量。

在 Azure AI 搜索中,矢量存储具有定义矢量和非矢量字段的索引架构、用于创建嵌入空间的算法的矢量配置,以及查询请求中使用的矢量字段定义的设置。 创建索引 API 将创建矢量存储。

如果没有 Azure 订阅,请在开始前创建一个试用版订阅

注意

本快速入门省略了矢量化步骤,并在示例文档中提供了嵌入内容。 如果要添加基于你自己的内容的内置数据分块和矢量化功能,请尝试使用“导入和矢量化数据”向导进行端到端演练。

先决条件

下载文件

从 GitHub 下载 REST 示例以发送本快速入门中的请求。 有关详细信息,请参阅从 GitHub 下载文件

你还可以在本地系统上启动一个新文件,并根据本文中的说明手动创建请求。

获取搜索服务终结点

你可以在 Azure 门户中找到搜索服务终结点。

  1. 登录到 Azure 门户查找你的搜索服务

  2. 在“概述”主页上,找到相应 URL。 示例终结点可能类似于 https://mydemo.search.azure.cn

    概述页面上 URL 属性的屏幕截图。

在稍后的步骤中,需将此终结点粘贴到 .rest.http 文件中。

配置访问权限

搜索终结点的请求必须经过身份验证和授权。 你可以使用 API 密钥或角色来完成此任务。 密钥更容易上手,但角色更安全。

对于基于角色的连接,如果按照以下说明操作,你将通过自己的标识(而不是客户端应用的标识)连接到 Azure AI 搜索。

选项 1:使用密钥

选择“设置”>“密钥”,然后复制管理密钥。 管理密钥用于添加、修改和删除对象。 有两个可互换的管理密钥。 复制其中任意一个。 有关详细信息,请参阅使用密钥身份验证连接到 Azure AI 搜索

显示 Azure 门户中的 API 密钥的屏幕截图。

在稍后的步骤中,需将此密钥粘贴到 .rest.http 文件中。

选项 2:使用角色

请确保为基于角色的访问配置搜索服务。 你必须已预先配置用于实现开发人员访问的角色分配。 角色分配必须授予创建、加载和查询搜索索引的权限。

在本部分中,使用 Azure CLI、Azure PowerShell 或 Azure 门户获取个人标识令牌。

  1. 登录到 Azure CLI。

    az cloud set -n AzureChinaCloud
    az login
    # az cloud set -n AzureCloud   //means return to Public Azure.
    
  2. 获取个人标识令牌。

    az account get-access-token --scope https://search.azure.com/.default
    

在稍后的步骤中,需将个人标识令牌粘贴到 .rest.http 文件中。

注意

本部分假定你使用的是代表你连接到 Azure AI 搜索的本地客户端。 另一种方法是获取客户端应用的令牌,前提是你的应用程序已在 Microsoft Entra ID 中注册

创建矢量索引

创建索引 (REST) 创建矢量索引并在搜索服务上设置物理数据结构。

索引架构围绕酒店内容进行组织。 示例数据由矢量和非矢量名称以及七家虚构酒店的描述组成。 该架构包括矢量索引和查询以及语义排名的配置。

  1. 在 Visual Studio Code 中打开新的文本文件。

  2. 将变量设置为之前收集的值。 此示例使用了个人标识令牌。

    @baseUrl = PUT-YOUR-SEARCH-SERVICE-URL-HERE
    @token = PUT-YOUR-PERSONAL-IDENTITY-TOKEN-HERE
    
  3. 使用 .rest.http 文件扩展名保存文件。

  4. 粘贴以下示例,以在搜索服务上创建 hotels-vector-quickstart 索引。

    ### Create a new index

                }
            ],
            "profiles": [      
                {
                    "name": "my-vector-profile",
                    "algorithm": "my-hnsw-vector-config-1"
                }
          ]
        }
    }
    
  5. 选择“发送请求”。 回想一下,你需要 REST 客户端发送请求。 应具有 HTTP/1.1 201 Created 响应。 响应正文应包含索引架构的 JSON 表示形式。

    要点:

    • fields 集合包含文本和矢量搜索所需的关键字段、文本字段和矢量字段(例如 DescriptionDescriptionVector)。 将矢量字段和非矢量字段并置在同一索引中可实现混合查询。 例如,可以将筛选器、带语义排名的文本搜索和矢量合并到单个查询操作中。
    • 矢量字段必须是带有 dimensionsvectorSearchProfiletype: Collection(Edm.Single)
    • vectorSearch 部分是一组最近的邻域算法配置和配置文件的数组。 支持的算法包括分层可导航小世界和穷举 k 最近邻域。 有关详细信息,请参阅矢量搜索中的相关性评分

上传文档

创建和加载索引是两个独立的步骤。 在 Azure AI 搜索中,索引包含所有可搜索的数据,并且查询在搜索服务上运行。 对于 REST 调用,数据以 JSON 文档的形式提供。 为此任务使用文档 - 索引 REST API

会扩展 URI 以包含 docs 集合和 index 操作。

重要

以下示例不是可运行的代码。 为了便于阅读,我们排除了矢量值,因为每个矢量值包含 1536 个嵌入,这对于本文而言太长了。 如果你要尝试执行此步骤,请从 GitHub 上的示例中复制可运行的代码。

要点:

  • 有效负载中的文档由索引架构中定义的字段组成。
  • 矢量字段包含浮点值。 dimensions 属性的最小值为 2,每个字段不超过 3072 个浮点值。 本快速入门将 dimensions 属性设置为 1536,因为这是 Azure OpenAI text-embedding-ada-002 模型生成的嵌入项的大小。

运行查询

加载文档后,可以使用文档 - 搜索 POST (REST) 对其发出矢量查询。

有几个查询可用于演示各种模式:

本部分中的矢量查询基于两个字符串:

  • 搜索字符串historic hotel walk to restaurants and shopping
  • 矢量查询字符串(矢量化为数学表示形式):classic lodging near running trails, eateries, retail

重要

以下示例是不可运行的代码。 为了便于阅读,我们排除了矢量值,因为每个数组值包含 1536 个嵌入,这对于本文而言太长了。 如果你要尝试这些查询,请从 GitHub 上的示例中复制可运行的代码。

  1. 粘贴 POST 请求以查询搜索索引。 然后,选择“发送请求”。 URI 扩展为包含 /docs/search 运算符。

    ### Run a query
    POST {{baseUrl}}/indexes/hotels-vector-quickstart/docs/search?api-version=2023-11-01  HTTP/1.1
        Content-Type: application/json
        Authorization: Bearer {{token}}
    
        {
            "count": true,
            "select": "HotelId, HotelName, Description, Category",
            "vectorQueries": [
                {
                    "vector"": [0.01944167, 0.0040178085
                        . . .  TRIMMED FOR BREVITY
                        010858015, -0.017496133],
                    "k": 7,
                    "fields": "DescriptionVector",
                    "kind": "vector",
                    "exhaustive": true
                }
            ]
        }
    

    为简洁起见,缩短了此矢量查询。 vectorQueries.vector 包含查询输入的矢量化文本,fields 确定要搜索的矢量字段,k 指定要返回的最近邻域的数目。

    矢量查询字符串为 classic lodging near running trails, eateries, retail,该字符串将矢量化为此查询的 1536 个嵌入项。

  2. 查看回应。 等效于 classic lodging near running trails, eateries, retail 的矢量的响应包括 7 个结果。 每个结果都提供一个搜索分数和 select 中列出的字段。 在相似性搜索中,响应总是包含按相似性分数值排序的 k 个结果。

使用筛选器的单矢量搜索

可以添加筛选器,但筛选器将应用于索引中的非矢量内容。 在此示例中,筛选器适用于 Tags 字段,可筛选出任何不提供免费 Wi-Fi 的酒店。

  1. 粘贴 POST 请求以查询搜索索引。

    ### Run a vector query with a filter
    POST {{baseUrl}}/indexes/hotels-vector-quickstart/docs/search?api-version=2023-11-01  HTTP/1.1
        Content-Type: application/json
        Authorization: Bearer {{token}}
    
        {
            "count": true,
            "select": "HotelId, HotelName, Category, Tags, Description",
            "filter": "Tags/any(tag: tag eq 'free wifi')",
            "vectorFilterMode": "postFilter",
            "vectorQueries": [
            {
                "vector": [ VECTOR OMITTED ],
                "k": 7,
                "fields": "DescriptionVector",
                "kind": "vector",
                "exhaustive": true
            },
        ]
    }
    
  2. 查看回应。 查询与前面的示例相同,但包含后处理排除筛选器,仅返回具有免费 Wi-Fi 的三家酒店。

    {
    
        "@odata.count": 3,
        "value": [

                ]
            }
        ]
    }
    

混合搜索由单个搜索请求中的关键字查询和矢量查询组成。 此示例并发运行矢量查询和全文搜索:

  • 搜索字符串historic hotel walk to restaurants and shopping
  • 矢量查询字符串(矢量化为数学表示形式):classic lodging near running trails, eateries, retail
  1. 粘贴 POST 请求以查询搜索索引。 然后,选择“发送请求”。

    ### Run a hybrid query
    POST {{baseUrl}}/indexes/hotels-vector-quickstart/docs/search?api-version=2023-11-01  HTTP/1.1
        Content-Type: application/json
        Authorization: Bearer {{token}}
    
    {
        "count": true,
        "search": "historic hotel walk to restaurants and shopping",
        "select": "HotelName, Description",
        "top": 7,
        "vectorQueries": [
            {
                "vector": [ VECTOR OMITTED],
                "k": 7,
                "fields": "DescriptionVector",
                "kind": "vector",
                "exhaustive": true
            }
        ]
    }
    

    由于这是混合查询,因此结果按倒数排名融合 (RRF) 进行排名。 RRF 评估多个搜索结果的搜索分数,采用反函数,然后合并和排序组合的结果。 返回 top 结果数。

    由于 RRF 合并了结果,因此这有助于查看输入。 以下结果仅来自全文查询。 前两个结果是 Sublime Cliff Hotel 和 History Lion Resort。 Sublime Cliff Hotel 具有更强的 BM25 相关性评分。

    在使用 HNSW 查找匹配项的纯矢量查询中,Sublime Cliff Hotel 跌至第四位。 History Lion Resort 是全文搜索的第二位和矢量搜索的第三位,并没有经历相同的波动范围,因此在均匀化结果集中显示为顶级匹配。
