求助elasticsearch聚合查询结果差异

以下两种查询理论结果应该一致，但是不明白为什么查到的结果不一样。
一、第一种查询方式：

GET */_search?size=0
{
  "track_total_hits": true, 
  "aggs": {
    "range": {
      "date_range": {
        "field": "@timestamp",
        "format": "yyyy-MM-dd HH:mm:ss",
        "ranges": [
          {
            "from": "now-1m/m",
            "to": "now"
          }
        ]
      }
    }
  }
}

结果：

{
  "took" : 9899,
  "timed_out" : false,
  "_shards" : {
    "total" : 93,
    "successful" : 93,
    "skipped" : 0,
    "failed" : 0
  },
  "hits" : {
    "total" : {
      "value" : 149443090,
      "relation" : "eq"
    },
    "max_score" : null,
    "hits" : [ ]
  },
  "aggregations" : {
    "range" : {
      "buckets" : [
        {
          "key" : "2023-11-01 02:20:00-2023-11-01 02:21:21",
          "from" : 1.6988052E12,
          "from_as_string" : "2023-11-01 02:20:00",
          "to" : 1.698805281507E12,
          "to_as_string" : "2023-11-01 02:21:21",
          "doc_count" : 9251
        }
      ]
    }
  }
}

二、第二种查询方式

{
            "track_total_hits": true,
            "query": {
                "range": {
                    "@timestamp": {
                        "from": "now-1m",
                        "to": "now",
                        "format": "yyyy-MM-dd HH:mm:ss.SSS",
                        "include_lower": true,
                        "include_upper": true,
                        "boost": 1
                    }
                }
            }
        }

结果：

{
  "took" : 52,
  "timed_out" : false,
  "_shards" : {
    "total" : 93,
    "successful" : 93,
    "skipped" : 0,
    "failed" : 0
  },
  "hits" : {
    "total" : {
      "value" : 815,
      "relation" : "eq"
    },
    "max_score" : null,
    "hits" : [ ]
  }
}
