Elasticsearch 索引类型在更新状态后没有改变

Question

我已经成功地进行了一些 _bulk 插入，现在我正在尝试使用日期范围进行查询并过滤如下内容：

{
   "query": {
        "bool": {
            "must": [{
                "terms": {
                    "mt_id": [613]
                }
            },
            {
                "range": {
                    "time": {
                        "gt": 1470009600000,
                        "lt": 1470009600000
                    }
                }
            }]
        }
    }

不幸的是我没有得到结果，现在我注意到索引映射是在批量插入之后创建的，如下所示：

{
  "agg__ex_2016_8_3": {
    "mappings": {
      "player": {
        "properties": {
          "adLoad": {
            "type": "long"
          },
         "mt_id": {
           "type": "long"
          },
          "time": {
            "type": "string"
          }
        }
      },

作为一种解决方案，我尝试使用以下方法更改索引映射：

PUT /agg__ex_2016_8_3/_mapping/player
{
  "properties" : {
    "mt_id" : {
      "type" :    "long",
      "index":    "not_analyzed"
    }
  }
}

得到

{
  "acknowledged": true
}

和 PUT /agg__ex_2016_8_3/_mapping/player

{
  "properties" : {
    "time" : {
      "type" :    "date",
     "format" : "yyyy/MM/dd HH:mm:ss"
    }
  }
}

得到：

{
   "error": {
      "root_cause": [
         {
            "type": "remote_transport_exception",
            "reason": "[vj_es_c1-esc13][10.132.69.145:9300][indices:admin/mapping/put]"
         }
      ],
      "type": "illegal_argument_exception",
      "reason": "mapper [time] of different type, current_type [string], merged_type [date]"
   },
   "status": 400
}

但是什么也没发生，仍然没有得到任何结果。

我做错了什么？ （我必须使用 http，而不是 curl）

谢谢！！

Answer 1

试试这个：

# 1. delete index
DELETE agg__ex_2016_8_3

# 2. recreate it with the proper mapping
PUT agg__ex_2016_8_3
{
  "mappings": {
    "player": {
      "properties": {
        "adLoad": {
          "type": "long"
        },
        "mt_id": {
          "type": "long"
        },
        "time": {
          "type": "date"
        }
      }
    }
  }
}

# 3. create doc
PUT agg__ex_2016_8_3/player/104
{
  "time": "1470009600000",
  "domain": "organisemyhouse.com",
  "master_domain": "613###organisemyhouse.com",
  "playerRequets": 4,
  "playerLoads": 0,
  "c_Id": 0,
  "cb_Id": 0,
  "mt_Id": 613
}

# 4. search
POST agg__ex_2016_8_3/_search
{
  "query": {
    "bool": {
      "must": [
        {
          "terms": {
            "mt_Id": [
              613
            ]
          }
        },
        {
          "range": {
            "time": {
              "gte": 1470009600000,
              "lte": 1470009600000
            }
          }
        }
      ]
    }
  }
}
