Question

大家好，到目前为止，我一直没有运气，要汇总展示次数的总展示次数字段，但我不断收到错误。我收到了以下问题：

 GET smarttag-2016.06.28.*/_search?search_type=count
{
  "query": {
    "bool": {
      "must": [{
        "range": {
          "@timestamp": {
            "gte": "2016-06-28T10:00:00",
            "lt": "2016-06-28T11:00:00"
          }
        }
      }],
      "must_not": [
        {
          "term": {
            "tagType": {
              "value": "app"
            }
          }
        }
      ]
    }
  },
  "aggs": {
    "TagId": {
      "terms": {
        "field": "TagId",
        "size": 0
      },
      "aggs": {
        "name": {
          "terms": {
            "field": "url",
            "size": 0
          },
          "aggs": {
            "tagType": {
              "terms": {
                "field": "type"
              },
              "aggs": {
                "impressions": {
                  "sum": {
                    "field": "imp"
                  }
                }
              }
            }
          } 
        }
      }
    },
    "sum_imp": {
      "sum_bucket": {
          "buckets_path": "TagId>name>tagType>impressions"
          }
      }
  }
}

错误：

  {
       "error": {
          "root_cause": [],
          "type": "reduce_search_phase_exception",
          "reason": "[reduce] ",
          "phase": "query",
          "grouped": true,
          "failed_shards": [],
          "caused_by": {
             "type": "aggregation_execution_exception",
             "reason": "buckets_path must reference either a number value or a single value numeric metric aggregation, got: java.lang.Object[]"
          }
       },
       "status": 503
    }

我不明白我做错了什么。

Answer 1

我认为该问题与＆＃34; TagId＆gt;名称＆gt; tagType＆gt;展示次数相关＆＃34; 部分。即管道桶聚合下降超过2个级别。我希望你已经解决了这个问题。我也面对这个。

聚合聚合字段的总和
