如何将此Elasticsearch查询从2.x转换为5.x索引？

Question

Our system upgraded elasticsearch from 2.x to 5.x. Now query's are not working in 5.x written in 2.x. So I have to convert elasticsearch query from 2.x to 5.x index?

Please suggest how to convert this query to elasticsearch 5.x query? _score field will not be affected and able to cache this query.

{
  "size": 12,
  "query": {
    "filtered": {
      "filter": {
        "bool": {
          "must": [
            {
              "term": {
                "pageType": "ulp_comb"
              }
            },
            {
              "range": {
                "date": {
                  "gte": "2017-09"
                }
              }
            }
          ],
          "must_not": [
            {
              "term": {
                "entityId": 0
              }
            }
          ]
        }
      }
    }
  }
}

You just need to change filtered to bool

{
  "size": 12,
  "query": {
    "bool": { // change to bool
      "filter": {
        "bool": {
          "must": [
            {
              "term": {
                "pageType": "ulp_comb"
              }
            },
            {
              "range": {
                "date": {
                  "gte": "2017-09"
                }
              }
            }
          ],
          "must_not": [
            {
              "term": {
                "entityId": 0
              }
            }
          ]
        }
      }
    }
  }
}

Hope it helps
