如何在java中构建elasticsearch词条查询？

import org.elasticsearch.action.search.SearchRequest;
import org.elasticsearch.action.search.SearchResponse;
import org.elasticsearch.client.RequestOptions;
import org.elasticsearch.client.RestHighLevelClient;
import org.elasticsearch.index.query.QueryBuilders;
import org.elasticsearch.search.builder.SearchSourceBuilder;

public class ElasticsearchQueryExample {
    public static void main(String[] args) {
        // 创建Elasticsearch客户端
        RestHighLevelClient client = new RestHighLevelClient();

        // 创建查询请求
        SearchRequest searchRequest = new SearchRequest("index_name");
        SearchSourceBuilder searchSourceBuilder = new SearchSourceBuilder();

        // 构建词条查询
        searchSourceBuilder.query(QueryBuilders.termQuery("field_name", "search_term"));

        // 设置查询请求的源
        searchRequest.source(searchSourceBuilder);

        try {
            // 执行查询请求
            SearchResponse searchResponse = client.search(searchRequest, RequestOptions.DEFAULT);

            // 处理查询结果
            // ...

            // 关闭Elasticsearch客户端
            client.close();
        } catch (Exception e) {
            e.printStackTrace();
        }
    }
}
