elasticsearch 聚合函数求和、求平均值

按 dlmc 字段分组，对 tbmj 字段求和、求平均值

{
    "aggs": {
        "group_by_dlmc_sum": {
            "terms": {
                "size": 1000,
                "field": "dlmc.keyword"
            },
            "aggs": {
                "tbmj_sum": {
                    "sum": {
                        "field": "tbmj"
                    }
                }
            }
        },
        "group_by_dlmc_avg": {
            "terms": {
                "size": 1000,
                "field": "dlmc.keyword"
            },
            "aggs": {
                "tbmj_avg": {
                    "avg": {
                        "field": "tbmj"
                    }
