按基数过滤

我正在运行此嵌套聚合以获取与候选人相关联的所有组 -

"aggs" : { "remove_empty":{  "filter": { "not": { "term": {"candidate_id":"NA"}} }, "aggs": {  "distinct_ids":{ "terms":{ "field":"candidate_id"}, "aggs":{ "distinct_groups":{  "terms":{ "field":"candidate_group" }}}} }  } }

返回预期结果 -

"aggregations":{  
      "remove_empty":{  
         "doc_count":160322,
         "distinct_ids":{  
            "doc_count_error_upper_bound":0,
            "sum_other_doc_count":0,
            "buckets":[  
               {  
                  "key":"1401",
                  "distinct_groups":{  
                     "doc_count_error_upper_bound":0,
                     "sum_other_doc_count":0,
                     "buckets":[  
                        {  
                           "key":"group4",
                           "doc_count":619
                        }
                     ]
                  }
               },
               {  
                  "key":"1402",
                  "distinct_groups":{  
                     "doc_count_error_upper_bound":0,
                     "sum_other_doc_count":0,
                     "buckets":[  
                        {  
                           "key":"group1",
                           "doc_count":619
                        },
                        {  
                           "key":"group6",
                           "doc_count":619
                        }
                     ]
                  }
               },
               {  
                  "key":"1403",
                  "distinct_groups":{  
                     "doc_count_error_upper_bound":0,
                     "sum_other_doc_count":0,
                     "buckets":[  
                        {  
                           "key":"group3",
                           "doc_count":619
                        }
                     ]
                  }
               },
               {  
                  "key":"1404",
                  "distinct_groups":{  
                     "doc_count_error_upper_bound":0,
                     "sum_other_doc_count":0,
                     "buckets":[  
                        {  
                           "key":"group6",
                           "doc_count":619
                        }
                     ]
                  }
               }
            ]
         }
      }
   }

但是，我只需要与两个或更多组相关联的candidate_id -

{  
  "key":"1402",
  "distinct_groups":{  
     "doc_count_error_upper_bound":0,
     "sum_other_doc_count":0,
     "buckets":[  
        {  
           "key":"group1",
           "doc_count":619
        },
        {  
           "key":"group6",
           "doc_count":619
        }
     ]
  }
}

有没有办法按基数过滤＆gt;这个查询中有1个？
