需求： 颜色+品牌下钻分析时按最深层metric进行排序

先看下默认的排序规则：

GET /tvs/sales/_search
{"aggs": {"group_by_color": {"terms": {"field": "color"},# 在color这个bucket下 下钻 品牌"aggs": {"group_by_brand": {"terms": {"field": "brand"},# 在brand这个b下 bcketmetrics 求 avg"aggs": {"avg_price": {"avg": {"field": "price"}}}}}}},"size": 0
}

{"took": 1,"timed_out": false,"_shards": {"total": 5,"successful": 5,"skipped": 0,"failed": 0},"hits": {"total": 8,"max_score": 0,"hits": []},"aggregations": {"group_by_color": {"doc_count_error_upper_bound": 0,"sum_other_doc_count": 0,"buckets": [{"key": "红色","doc_count": 4,"group_by_brand": {"doc_count_error_upper_bound": 0,"sum_other_doc_count": 0,"buckets": [{"key": "长虹","doc_count": 3,"avg_price": {"value": 1666.6666666666667}},{"key": "三星","doc_count": 1,"avg_price": {"value": 8000}}]}},{"key": "绿色","doc_count": 2,"group_by_brand": {"doc_count_error_upper_bound": 0,"sum_other_doc_count": 0,"buckets": [{"key": "TCL","doc_count": 1,"avg_price": {"value": 1200}},{"key": "小米","doc_count": 1,"avg_price": {"value": 3000}}]}},{"key": "蓝色","doc_count": 2,"group_by_brand": {"doc_count_error_upper_bound": 0,"sum_other_doc_count": 0,"buckets": [{"key": "TCL","doc_count": 1,"avg_price": {"value": 1500}},{"key": "小米","doc_count": 1,"avg_price": {"value": 2500}}]}}]}}
}

截取下Red 来看下默认的排序规则（doc_count 降序）

如果想按照平均价格降序排列呢？ 我们这里有2层下钻，而平均价格是在第二层下钻里，即我们这里的主题【按最深层metric进行排序】

GET /tvs/sales/_search
{"aggs": {"group_by_color": {"terms": {"field": "color"},"aggs": {"group_by_brand": {"terms": {"field": "brand","order": {"avg_price": "desc"}},"aggs": {"avg_price": {"avg": {"field": "price"}}}}}}},"size": 0
}

返回结果：

{"took": 2,"timed_out": false,"_shards": {"total": 5,"successful": 5,"skipped": 0,"failed": 0},"hits": {"total": 8,"max_score": 0,"hits": []},"aggregations": {"group_by_color": {"doc_count_error_upper_bound": 0,"sum_other_doc_count": 0,"buckets": [{"key": "红色","doc_count": 4,"group_by_brand": {"doc_count_error_upper_bound": 0,"sum_other_doc_count": 0,"buckets": [{"key": "三星","doc_count": 1,"avg_price": {"value": 8000}},{"key": "长虹","doc_count": 3,"avg_price": {"value": 1666.6666666666667}}]}},{"key": "绿色","doc_count": 2,"group_by_brand": {"doc_count_error_upper_bound": 0,"sum_other_doc_count": 0,"buckets": [{"key": "小米","doc_count": 1,"avg_price": {"value": 3000}},{"key": "TCL","doc_count": 1,"avg_price": {"value": 1200}}]}},{"key": "蓝色","doc_count": 2,"group_by_brand": {"doc_count_error_upper_bound": 0,"sum_other_doc_count": 0,"buckets": [{"key": "小米","doc_count": 1,"avg_price": {"value": 2500}},{"key": "TCL","doc_count": 1,"avg_price": {"value": 1500}}]}}]}}
}

同样的，我们也截取下Red 来看下默认的排序规则（doc_count 降序）

已经按照我们指定的 avg_price 降序排列啦。
