es-Range Aggregation(範圍聚合)

A multi-bucket value source based aggregation that enables the user to define a set of ranges－每一個表明一個bucket。

在聚合過程當中，從每一個文件中提取的值將根據每一個存儲區範圍進行檢查，並對相關/匹配文檔進行「bucket」，值得注意的是，注意，此聚合包含了from值，不包括每一個範圍的to的值。

例子：

{
    "aggs" : {
        "price_ranges" : {
            "range" : {
                "field" : "price",
                "ranges" : [
                    { "to" : 50 },
                    { "from" : 50, "to" : 100 },
                    { "from" : 100 }
                ]
            }
        }
    }
}

響應結果：

{
    ...
 
    "aggregations": {
        "price_ranges" : {
            "buckets": [
                {
                    "to": 50,
                    "doc_count": 2
                },
                {
                    "from": 50,
                    "to": 100,
                    "doc_count": 4
                },
                {
                    "from": 100,
                    "doc_count": 4
                }
            ]
        }
    }
}
