Why my search slow?

Elastic Stack Elasticsearch
1

I upgrade my es cluster to 5.5 and have following mapping:

    "append": {
      "type": "short"
    },
    "comment": {
      "type": "text",
      "index": "analyzed"
    },
    "create_time": {
      "type": "date"
    },
    "desc_score": {
      "type": "integer"
    },
    "goods_id": {
      "type": "long"
    },
    "goods_name": {
      "type": "keyword",
      "index": "not_analyzed"
    },
    "handler": {
      "type": "keyword",
      "index": "not_analyzed"
    },
    "is_first_review": {
      "type": "short"
    },
    "logistic_score": {
      "type": "integer"
    },
    "mall_id": {
      "type": "long"
    },
    "order_id": {
      "type": "long"
    },
    "order_sn": {
      "type": "keyword",
      "index": "not_analyzed"
    },
    "parent_id": {
      "type": "keyword",
      "index": "not_analyzed"
    },
    "review_id": {
      "type": "long"
    },
    "score": {
      "type": "integer"
    },
    "service_score": {
      "type": "integer"
    },
    "shipping_id": {
      "type": "long"
    },
    "shipping_name": {
      "type": "keyword",
      "index": "not_analyzed"
    },
    "status": {
      "type": "short"
    },
    "tracking_number": {
      "type": "keyword",
      "index": "not_analyzed"
    },
    "update_time": {
      "type": "date"
    },
    "user_id": {
      "type": "long"
    }

When I profile in kibana with the following statement and got the result in the picture.

{
      "from": 0,
      "size": 10,
      "query": {
      "bool": {
      "filter": [
        {
          "terms": {
            "goods_id": [

            ],
            "boost": 1.0
          }
        },
        {

        },
        {

              "boost": 1.0
            }
          }
        }
      ],
      "disable_coord": false,
      "adjust_pure_negative": true,
      "boost": 1.0
    }
  },

    {

      }
    }

I add profile=true to the search clause and get the following profile result(total 18 shards, I only copy one shard result here):

      ],

As you see type is null for status filter, any one know why type is null?
