是否可以将doc_count用作弹性搜索中的术语？

Question

我正在尝试显示有多少用户从一个视图列表中查看过一次，两次......的内容。

看起来像是：

1 view: 1000 users
2 views: 100 users
3 views: 10 users
...

我可以像这样获得每个用户的观看量：

//request
{
  "size": 0,
  "aggs": {
    "views per token": {
      "terms": {
        "field": "browsertoken",
        "size": 0,
        "order": {
          "_count": "desc"
        }
      }
    }
  }
}
//returns
{
   "took": 61,
   "timed_out": false,
   ...
   "hits": {
      "total": 215642,
      "max_score": 0,
      "hits": []
   },
   "aggregations": {
     "actions per token": {
     "doc_count_error_upper_bound": 0,
     "sum_other_doc_count": 0,
     "buckets": [
        {
           "key": "co8976vymgarwwmianljqcch83ufecdi",
           "doc_count": 2479
        },
        {
           "key": "t2vc9j056fkihpvic0ty0rzzq7low29",
           "doc_count": 369
        },
   ...

但是如何获得此聚合结果的doc_count的计数？
