Java Spring数据elasticsearch子聚合未在聚合结果中提供父子结果

我正在使用spring数据elastisearch并构造了一个带有子聚集的查询。当我调试和复制所创建查询的值并从sense plugin/postman执行时，我通过对两个字段（即一个字段在另一个字段中）的子聚合得到正确的结果，但是程序返回的响应不包含另一个字段在另一个字段中，而只包含聚合结果中的父级字段

你能告诉我我可能做错了什么吗。请参阅下文，了解更多信息

文档骨架类似于

{
    ...
    "gender":"Men",
    "category":"Shirts",
    .....
} ,
{
    ...
    "gender":"Men",
    "category":"Pants",
    .....
},
{
    ...
    "gender":"Women",
    "category":"Pants",
    .....
} 

...

"aggregations": {
      "gender": {
         "doc_count_error_upper_bound": 0,
         "sum_other_doc_count": 0,
         "buckets": [
            {
               "key": "Men",
               "doc_count": 4,
               "category": {
                  "buckets": [
                     {
                        "key": "shirts",
                        "doc_count": 2
                     },
                     {
                        "key": "pants",
                        "doc_count": 2
                     }
                     ]
                }
            },
            {
               "key": "Women",
               "doc_count": 2,
               "category": {              
                  "buckets": [
                     {
                        "key": "pants",
                        "doc_count": 2
                     }
                     ]
                }
            }
        ]
    }

 }
 ....

等等

聚合中的预期输出如下

{
    ...
    "gender":"Men",
    "category":"Shirts",
    .....
} ,
{
    ...
    "gender":"Men",
    "category":"Pants",
    .....
},
{
    ...
    "gender":"Women",
    "category":"Pants",
    .....
} 

...

"aggregations": {
      "gender": {
         "doc_count_error_upper_bound": 0,
         "sum_other_doc_count": 0,
         "buckets": [
            {
               "key": "Men",
               "doc_count": 4,
               "category": {
                  "buckets": [
                     {
                        "key": "shirts",
                        "doc_count": 2
                     },
                     {
                        "key": "pants",
                        "doc_count": 2
                     }
                     ]
                }
            },
            {
               "key": "Women",
               "doc_count": 2,
               "category": {              
                  "buckets": [
                     {
                        "key": "pants",
                        "doc_count": 2
                     }
                     ]
                }
            }
        ]
    }

 }
 ....

Java代码用于添加术语聚合类型的子聚合

        for (Object aggregationField : request.getAggregationFields()) {
            TermsBuilder termBuilder = AggregationBuilders.terms(aggregationField.toString())
                    .field(aggregationField.toString()).size(0);
            if(aggregationField.toString().equals("gender"))
            {
                TermsBuilder platformBuilder = AggregationBuilders.terms("category").field("category").size(0);
                termBuilder.subAggregation(platformBuilder);
            }               
            nativeSearchQueryBuilder.addAggregation(termBuilder);
        }
