azure - 从 Azure 认知搜索索引中删除文档

Question

我在 azure 认知搜索索引中有一个名为文档名称的索引。该索引中的文档如下所示

{
  "@search.score": 1,
  "id": "3412b974-ca9e-4bce-a592-78084a71e4c6",
  "content": null,

        }
      ]
    }
  ]
}

我想根据 documentId 从此索引中删除文档。但是，documentId 不是该索引中的主键。Id 是主键。我在 Express 中使用 azure sdk 来实现此目的。 任何帮助将不胜感激。

我尝试过以下方法:

1. 我对字段 documentId 进行搜索以首先获取文档，然后删除这些文档。 [由于不必要地获取文档而付出额外的努力]
2. 尝试使用 action.delete 进行删除，但它需要主键，而 documentId 不是主键。

由于您使用的是 Azure 认知搜索，并且希望根据 documentId 删除文档，该 documentId 不是主键，但仍需要用于删除，因此您可以利用 Key-As-Payload 方法来删​​除文件。在此方法中，您可以将 documentId 设置为要删除的文档的主键 Id 字段的值。下面介绍了如何使用 Express 中的 Azure 认知搜索 SDK 实现此目的:

const { SearchClient, AzureKeyCredential } = require("@azure/search-documents");

// Replace the following values with your actual Azure Cognitive Search credentials and configuration
const searchServiceName = "your-search-service-name";
const indexName = "your-index-name";
const apiKey = "your-admin-api-key"; // Ensure that this key has delete permissions

const credentials = new AzureKeyCredential(apiKey);
const searchClient = new SearchClient(searchServiceName, indexName, credentials);

async function deleteDocumentByDocumentId(documentId) {
  // Use documentId as the value of the 'Id' field for deletion
  const documentToDelete = { Id: documentId };

  try {
    await searchClient.deleteDocuments([documentToDelete]);
    console.log(`Document with documentId ${documentId} deleted successfully.`);
  } catch (err) {
    console.error(`Error deleting document with documentId ${documentId}:`, err);
  }
}

// Call the deleteDocumentByDocumentId function with the desired documentId to delete
const documentIdToDelete = "3d8c0912-e292-483f-80a2-5e63c57b9504";
deleteDocumentByDocumentId(documentIdToDelete);
