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

```auto
[
    {
        "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.
