I'm looking to do a Max aggregation on a value of the property under my document, the property is a list of complex object (key and value). Here's my data:

```auto
[{
    "id" : "1",
    "listItems" : 
        [
            {
                "key" : "li1",
                "value" : 100
            },
            {
                "key" : "li2",
                "value" : 5000
            }
        ]
},
{
    "id" : "2",
    "listItems" : 
        [
            {
                "key" : "li3",
                "value" : 200
            },
            {
                "key" : "li2",
                "value" : 2000
            }
        ]
}]

```

When I do the Nested Max Aggregation on "listItems.value", I'm expecting the max value returned to be 200 (and not 5000), reason being I want the logic to first figure the MIN value under listItems for each document, then doing the Max Aggregation on that. Is it possible to do something like this?

Thanks.

Try using a `min` aggregation first, and then use the [max bucket aggregation](https://www.elastic.co/guide/en/elasticsearch/reference/7.9/search-aggregations-pipeline-max-bucket-aggregation.html).
