I have a quick question about passing the filters key to the scripted language from parent aggregate to child aggregate.

Basically, I have defined the filters as below, In my scripted query, I want to use the filter key month as part of the DOM average calculation. In my example, I have hardcoded a date value, but it should be the key value of the filters definition. Would appreciate it if anyone could give me some feedback on how that could be worked out.
