RangeFacet基于时间戳字段

Question

有人可以告诉我如何在ElasticSearch enter code here中正确构建范围构面吗？我已经尝试了几种日期格式的变体，但总是得到异常。这是简单的版本：

{
  "facets": {
    "hdwm": {
      "range": {
        "field": "@timestamp",
        "ranges": [
          "{'to' : '2013-12-20' }",
          "{'from': '2013-12-20', 'to' : '2013-12-25' }",
          "{'from': '203-12-25' }"
        ]
      }
    }
  },
  "query": {
    "match_all": {}
  }
}

@timestamp字段定义为：

@timestamp: {
    format: dateOptionalTime
    type: date
}

并具有以下值：

@timestamp: 2013-11-20T01:20:37.527Z

Answer 1

以下为我工作。我想问题是关于'/“

的语法和用法

{
 "facets": {
    "hdwm": {
      "range": {
        "field": "@timestamp",
        "ranges": [
          {
            "to": "2013-12-30"
          },
          {
            "from": "2013-12-30",
            "to": "2013-12-31"
          },
          {
            "from": "2013-12-31"
          }
        ]
      }
    }
  },
  "query": {
    "match_all": {}
  }
}
