Aggregate query on filtered array of objects across documents

Elastic Stack Elasticsearch

Hi all,

I want to do a term aggregation on a field inside an array of objects, after filtering the array of objects on two other fields. For example, let's say I have the below documents in my database

[
    {
        "objects": [
            {
                "key1": 1,
                "key2": 2,
                "key3": 3
            }
        ]
    },
    {
        "objects": [
            {
                "key1": 1,
                "key2": 2,
                "key3": 4
            }
        ]
    },
    {
        "objects": [
            {
                "key1": 1,
                "key2": 5,
                "key3": 3
            }
        ]
    }
]

I want to do a "term" aggregation on key3 field where key1 and key2 are 1 and 2 respectively.

In this example, the query should return a count of 1 for 3 and 4 each.

The filter itself needs a nested and query and then I am stuck in figuring out how to build rest of the aggregate query inside it.
