假设我在同一索引中有很多文档，如下所示：
"_source": {
"customerId": "100",
"firstName": "XAaa",
"lastName": "XBbb",
"price": 10,
"revenue": 5
}
"_source": {
"customerId": "100",
"firstName": "XAaa",
"lastName": "XBbb",
"price": 20,
"revenue": 15
}
"_source": {
"customerId": "200",
"firstName": "YAaa",
"lastName": "yBbb",
"price": 110,
"revenue": 20
}....
如何使Elasticsearch聚合对来自同一customerId的值进行计数？
结果应该是这样的：
"_source": {
"customerId": "100",
"firstName": "XAaa",
"lastName": "XBbb",
"price": 30, // (10+20)
"revenue": 20 //(5+15)
}
"_source": {
"customerId": "200",
"firstName": "YAaa",
"lastName": "yBbb",
"price": 110,
"revenue": 20
}....
谢谢
