Question

我需要关于 ES 8.2.0 Java Api 客户端的 DeleteRequest 示例，我们没有类型。我们只有索引和文档。我正在寻找代码参考，我想通过传递索引名称和文档 ID 来删除一个特定文档。

Answer 1

你可以试试这个

语法：

DeleteRequest request = new DeleteRequest("your-index-name","doc-id");

示例：

DeleteRequest deleteRequest = new DeleteRequest("employeeindex","002");
DeleteResponse deleteResponse = client.delete(deleteRequest, RequestOptions.DEFAULT);
         System.out.println("response id: "+deleteResponse.getId());

Answer 2

您可以使用以下代码从索引中删除文档。您需要提供 index_name 和 doc_id 才能删除文档。

RestClient restClient = RestClient.builder(new HttpHost("localhost", 9200)).build();
ElasticsearchTransport transport = new RestClientTransport(restClient, new JacksonJsonpMapper());
ElasticsearchClient esClient = new ElasticsearchClient(transport);

DeleteRequest request = DeleteRequest.of(d -> d.index("index_name").id("doc_id"));
DeleteResponse response = esClient.delete(request);
