日期范围查询中的弹性搜索间隔

Question

I have a requirement where my query should be like this:

{
  "size": 0,
  "_source": [
    "dateCreated"
  ],
  "query": {
    "bool": {
      "must": {
        "range": {
          "date_published": {
            "from": "2019-01-01", //Fixed date
            "to": "--15 days from given 'from' date--" //Cannot find solution for this
          }
        }
      }
    }
  }
}

I could not find documentation for a simple requirement like this.

Using date math you can achieve what you expect

{
  "size": 0,
  "_source": [
    "dateCreated"
  ],
  "query": {
    "bool": {
      "must": {
        "range": {
          "date_published": {
            "from": "2019-01-01",
            "to": "2019-01-01||+15d"
          }
        }
      }
    }
  }
}
