Elasticsearch java api 使用别名查询

根据提供的引用内容，以下是使用Elasticsearch Java API进行别名查询的示例：

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 ElasticsearchAliasQueryExample {
    public static void main(String[] args) {
        // 创建RestHighLevelClient实例
        RestHighLevelClient client = new RestHighLevelClient();

        try {
            // 创建SearchRequest对象
            SearchRequest searchRequest = new SearchRequest("your_index_name");
            
            // 创建SearchSourceBuilder对象
            SearchSourceBuilder searchSourceBuilder = new SearchSourceBuilder();
            
            // 设置查询条件，这里使用别名查询
            searchSourceBuilder.query(QueryBuilders.termQuery("your_alias_name", "your_search_term"));
            
            // 将SearchSourceBuilder对象设置到SearchRequest中
            searchRequest.source(searchSourceBuilder);
            
            // 执行查询
            SearchResponse searchResponse = client.search(searchRequest, RequestOptions.DEFAULT);
            
            // 处理查询结果
            // ...

        } catch (IOException e) {
            e.printStackTrace();
        } finally {
            // 关闭RestHighLevelClient连接
            try {
                client.close();
            } catch (IOException e) {
                e.printStackTrace();
            }
        }
    }
}

请注意，上述示例中的"your_index_name"和"your_alias_name"需要替换为实际的索引名称和别名名称。"your_search_term"需要替换为您要搜索的实际术语。
