Elastic-Search Java-Rest-client 实现SQL的groupby后的orderby

ES在postman提交json数据，可以实现GroupBy后的OrderBy，post的data如下
有大神知道，在使用 elasticsearch-rest-client 怎么实现么？
目前我只能用java代码实现GroupBy，还实现不了OrderBy
代码环境
代码如下：
{
"size":0,
"aggs":{
"terms_age":{
"terms":{
"field":"age"
},
"aggs":{
"group_age":{
"sum":{
"field":"age"
}
},
"sort_by":{
"bucket_sort":{
"sort":[
{"group_age": {"order": "desc"}}
]
}
}
}
}
}

代码环境
- java 1.8
- elasticsearch-rest-client 6.1.3
代码如下：
SearchRequest searchRequest = new SearchRequest("test");
searchRequest.types("tester");
SearchSourceBuilder sourceBuilder = SearchSourceBuilder.searchSource();
searchRequest.source(sourceBuilder);
sourceBuilder.size(0);
AbstractAggregationBuilder builder = AggregationBuilders.terms("groupy_age").field("age");
AbstractAggregationBuilder subBuilder = AggregationBuilders.sum("sum_age").field("age");
builder.subAggregation(subBuilder);
sourceBuilder.aggregation(builder);
SearchResponse response = client.search(searchRequest);
