I want to get documents of a particular pattern in my aggregation. If I use termsAggregation then I can use "include" to mark a pattern but this is not the case with composite aggregation. I need use something like include to get all the documents of a particular pattern in composite aggregation. AfterKey doesn't work here because it doesn't support pattern only hard values. Could you please help me?
