我有一个索引在Azure认知搜索索引的文件名。此索引中的文档如下所示

我想根据documentId从该索引中删除文档。但是，documentId不是此索引中的主键。Id是主键。我在express中使用azure sdk。如果你能帮忙的话，我将不胜感激。
我尝试过以下方法：
1.我首先在字段documentId上运行了搜索以获取文档，然后删除了这些文档。[由于不必要的文件获取而需要额外的努力]
1.尝试使用action.delete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（不是主键，但仍需要用于删除）删除文档，因此可以利用Key-As-Payload方法来删除文档。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。以下是如何在Express中使用Azure认知搜索SDK实现此目标：

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);
