1、需求
统计指定品牌下每个颜色的销量
2、实现方式
SQL:
select count(*) from tvs.sales where brand like "%长%" group by price
GET /tvs/sales/_search
{
"size": 0,
"query": {
"match": {
"brand": "小米"
}
},
"aggs": {
"group_by_color": {
"terms": {
"field": "color"
}
}
}
}
结果:
{
"took": 107,
"timed_out": false,
"_shards": {
"total": 5,
"successful": 5,
"failed": 0
},
"hits": {
"total": 2,
"max_score": 0,
"hits": []
},
"aggregations": {
"group_by_color": {
"doc_count_error_upper_bound": 0,
"sum_other_doc_count": 0,
"buckets": [
{
"key": "绿色",
"doc_count": 1
},
{
"key": "蓝色",
"doc_count": 1
}
]
}
}
}
先进行搜索,对搜索出来的结果再次进行聚合
