Question

我有以下产品文档：

curl -XPOST -H 'Content-Type: application/json' "http://localhost:9200/test/_bulk?pretty" -d'
{"index":{"_index":"test","_type":"product"}}
{"id":"1", "price": "260" }
{"index":{"_index":"test","_type":"product"}}
{"id":"2", "price": "420" }
{"index":{"_index":"test","_type":"product"}}
{"id":"3", "price": "250" }

这些折扣文件：

curl -XPOST -H 'Content-Type: application/json' "http://localhost:9200/test/_bulk?pretty" -d'
{"index":{"_index":"test","_type":"discount"}}
{"product_id":"1", "group_id": 12, "percent": "50" }
{"index":{"_index":"test","_type":"discount"}}
{"product_id":"1", "group_id": 15, "percent": "20" }
{"index":{"_index":"test","_type":"discount"}}
{"product_id":"3", "group_id": 12, "percent": "10" }

我需要通过product_id和group_id键加入这两个文档。

在mysql数据库中将如下所示：

SELECT p.id, IF(d.percent > 0, p.price - (d.percent*p.price/100), p.price) price 
FROM product p
LEFT JOIN discount d ON p.id=d.product_id AND d.group_id=12
WHERE IF(d.percent > 0, p.price - (d.percent*p.price/100), p.price) < 210

该查询的结果将只有一行：

id => 1
price => 130

可以在elasticsearch中做吗？

在Elasticsearch中加入文件
