弹性搜索聚合十进制值的总和

Question

我需要计算索引为{“type”：long}的价格字段的总和。当我计算价格字段的总和时，它给我0而不是0.5。以下是我的json和聚合查询

{
    "_index": "test",
    "_type": "transaction",
    "_id": "uh5Z-6GBSUez1cRVl5dXpQ",
    "_score": 6.2806625,
    "_source": {
       "txn_id": "8982394",
       "team_id": "4234234234",       
       "price": 0.5,
       "tax": "0.00",
       "gross_price": "0.50",
       "payer_status": "unverified",
       "currency_code": "USD",
       "quantity": "1",             
       "payment_type": "paypal"
    }
}

我的聚合查询是

{
  "query": {
    "match": {
      "payment_type": "paypal"
    }
  },
  "aggs": {
    "daily_price_sum": {
      "sum": {
        "field": "price"
      }
    }
  }
}

查询输出

"aggregations": {
      "daily_price_sum": {
         "value": 0 // Here it is showing sum as 0 instead of 0.5 
      }

请帮我解决这个问题。谢谢        }

你提到价格是长型的。当提供0.5到一长的时间它会使数字四舍五入时，它不会以数学方式进行。因此存储的实际值不是0.5而是0.使它成为双倍。
