假设我有包含以下字段的文档:{field1, field2, ... fieldn}

Let's say I have documents with the following fields: {field1, field2, ... fieldn}

我需要运行一些查询，其中某些条件需要在两个或多个字段之间进行比较.像 fieldX = fieldY

I need to run some queries where some of the conditions will require a comparison between two or more fields. like fieldX = fieldY

在标准 SQL 中，一个例子可能是:

In standard SQL, an example could be:

SELECT * FROM Table1 WHERE farePrice>100 AND originRegion = destinationRegion

我一直在阅读一些文档，看起来脚本"可能是实现这一目标的唯一方法?或者还有其他选择吗?

I'be been reading some documentation, and it looks "scripting" could be the only way to achieve this? Or are there any other options?

推荐答案

可以使用脚本过滤器 -

You can use the script filter -

{ "filtered": { "query": { "range": { "farePrice": { "gt": 100 } } }, "filter": { "script": { "script": "doc['originRegion'].value == doc['destinationRegion'].value" } } } }
