How to sort in Elasticserch by the arithmetic difference of two fields
问题
可以按照两个字段之间的算术差异对Elasticsearch数据进行排序吗？
数据如下所示：
{
"id": "123",
"price": 500.0,
"discount": 10.0
}
我需要按照 price - discount 的差异对数据进行排序。
总体上说，这种排序是可行的吗？
我还对通过Java API实现它感兴趣。

The data are like this:

"price": 500.0,
"discount": 10.0,
}
And I need to sort the data by the difference price - discount.
Is it possible in general?
I am also interested in the implementation of it via Java API.
