我是弹性搜索的新手，我的问题是如何使用特定的必需字段查询弹性搜索以创建一个JSON字符串作为响应。
我正在使用Elastic Search Client API，并且已经使用Elastic Search Client连接到主机。
public class ElasticSearchClient {
private static final String HOST = EnvConf.getProperty("elastic.host");
private static final int PORT = EnvConf.getAsInteger("elastic.port");
private final RestHighLevelClient restClient;
public ElasticSearchClient() {
RestClientBuilder builder = RestClient.builder(
new HttpHost(HOST, PORT))
.setRequestConfigCallback(
requestConfigBuilder -> requestConfigBuilder
.setConnectTimeout(5000)
.setSocketTimeout(10000))
.setMaxRetryTimeoutMillis(30000);
restClient = new RestHighLevelClient(builder);
}
public IndexResponse index(String index , String type , XContentBuilder contentBuilder) throws IOException {
IndexRequest indexRequest = new IndexRequest(index, type)
.source(contentBuilder);
return restClient.index(indexRequest , RequestOptions.DEFAULT);
}
}
and this is the JSON of my elasticsearch:

我想添加另一个函数，该函数将在弹性搜索上执行查询命令并返回响应代码JSON类型。
所需字段为test_name，first_failure，jira_test_key
