rest client是不是不能拿来搜索数据？

我好像知道是啥原因了，光用QueryBuilder组装出来的查询语句没有还得用再套一层到query中去，rest cilent有提提供这样可以直接嵌套出的方法么。以前都是用transprotclient直接连续点出来的一堆。不想自己用stringbuilder拼接

都可以的，错误是什么？

我是用QueryBuilder组装了个boolBuilder查询然后：
HttpEntity entity = new NStringEntity(boolBuilder.toString(), ContentType.APPLICATION_JSON);
Response response=restClient.performRequest("GET", "/my_index/my_type/_search", Collections.<String, String>emptyMap(),entity);
 
获得报错如下:org.elasticsearch.client.ResponseException: GET http://localhost:9200/my_index/my_type/_search: HTTP/1.1 400 Bad Request
{"error":{"root_cause":[{"type":"parsing_exception","reason":"Unknown key for a START_OBJECT in [bool].","line":2,"col":12}],"type":"parsing_exception","reason":"Unknown key for a START_OBJECT in [bool].","line":2,"col":12},"status":400}
