Muliple nested queries and aggregations

Elastic Stack Elasticsearch

Hi,

ES 2.1.1

This post explains that when a nested sub-query is used in conjunction with aggregation on nested fields, that the sub-query needs to be repeated as a filter in the aggregation.

The documentation also stated that it is possible to have multiple nested sub-queries.

I have a case where a query contains multiple nested sub-queries (on the same nested object) within an overall query including non-nested fields. In boolean terms it looks as follows. History objects are the only nested objects in the mapping.

AND
    severity = urgent
    OR
        AND
            company.name = abc
            NESTED
                AND
                    history.created_at ≥ 2016-01-01
                    history.action_name = opened
        NESTED
            AND
                history.created_at ≥ 2015-06-01
                history.action_name = closed

The equivalent elastic query is here

My question is how to handle the multiple nested sub-queries in the aggregation clause if I want to aggregate on history.action_name?
