进阶-第43__深入聚合数据分析_排序：按每种颜色的平均销售额降序排序

 

之前的话，排序，是按照每个bucket的doc_count降序来排的

 

但是假如说，我们现在统计出来每个颜色的电视的销售额，需要按照销售额升序排序？？？？

搜索

{   "took": 2,   "timed_out": false,   "_shards": {     "total": 5,     "successful": 5,     "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": "蓝色",           "doc_count": 2,           "avg_price": {             "value": 2000           }         },         {           "key": "绿色",           "doc_count": 2,           "avg_price": {             "value": 2100           }         },         {           "key": "红色",           "doc_count": 4,           "avg_price": {             "value": 3250           }         }       ]     }   } }

 

结果

{   "took": 2,   "timed_out": false,   "_shards": {     "total": 5,     "successful": 5,     "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": "蓝色",           "doc_count": 2,           "avg_price": {             "value": 2000           }         },         {           "key": "绿色",           "doc_count": 2,           "avg_price": {             "value": 2100           }         },         {           "key": "红色",           "doc_count": 4,           "avg_price": {             "value": 3250           }         }       ]     }   } }
