让我们回到话题的原点,在进入新话题之前,对我们的示例做最后一个修改, 为每个汽车生成商计算最低和最高的价格:
GET /cars/transactions/_search
{
"size" : 0,
"aggs": {
"colors": {
"terms": {
"field": "color"
},
"aggs": {
"avg_price": { "avg": { "field": "price" }
},
"make" : {
"terms" : {
"field" : "make"
},
"aggs" : {
"min_price" : { "min": { "field": "price"} },
"max_price" : { "max": { "field": "price"} }
}
}
}
}
}
}{
...
"aggregations": {
"colors": {
"buckets": [
{
"key": "red",
"doc_count": 4,
"make": {
"buckets": [
{
"key": "honda",
"doc_count": 3,
"min_price": {
"value": 10000
},
"max_price": {
"value": 20000
}
},
{
"key": "bmw",
"doc_count": 1,
"min_price": {
"value": 80000
},
"max_price": {
"value": 80000
}
}
]
},
"avg_price": {
"value": 32500
}
},
...有了这两个桶,我们可以对查询的结果进行扩展并得到以下信息:
