Elasticsearch 聚合查询，分时间段求和

{
    "query": {
        "term": {
            "time_d": "20230508"
        }
    },
    "aggs": {
        "articles_over_time": {
            "date_histogram": {
                "field": "call_time",
                "interval": "hour"
            },
            "aggs": {
                "sum_total_number": {
                    "sum": {
                        "field": "total_number"
                    }
                }
            }
        }
    }
}

1、time_d 匹配值为 20230508 的记录

2、以 call_time（时间类型） 字段每小时分一个段

3、对 total_number 字段求和
