我索引了这2个文档：

POST my_index/my_type/1
{
    "name": "Nephi",
    "x": 5
}

POST my_index/my_type/2
{
    "name": "Lehi",
    "x": 10
}

下面是我的搜索请求：

POST my_index/my_type/_search?size=0
{
   "aggs": {
      "some_terms_agg": {
         "terms": {
            "field": "name",
            "order": {
               "the_script_bucket": "asc"
            }
         },
         "aggs": {
            "the_sum": {
               "sum": {
                  "field": "x"
               }
            },
            "the_avg": {
               "avg": {
                  "field": "x"
               }
            },
            "the_script_bucket": {
               "bucket_script": {
                  "buckets_path": {
                     "a": "the_sum.value",
                     "b": "the_avg.value"
                  },
                  "script": "a + b"
               }
            }
         }
      }
   }
}

我得到了这样的错误：
术语聚合器顺序路径[the_script_bucket]无效。未知聚合[the_script_bucket]
但是当我将the_script_bucket更改为the_sum或the_avg等其他聚合时，它工作正常。我确信这是因为the_script_bucket是一个管道聚合，但我希望基于the_script_bucket对术语进行排序，以便（例如）看到100，000个文档的前10个值。这可能吗？
