Nested Aggregation

More info about nested aggregation is in the official elasticsearch docs

A special single bucket aggregation that enables aggregating nested documents.

Simple example

{
    "aggregations" : {
        "agg_resellers" : {
            "nested" : {
                "path" : "resellers"
            },
            "aggregations" : {
                "agg_min_price" : { "min" : { "field" : "resellers.price" } }
            }
        }
    }
}

And now the query via DSL:

$minAggregation = new MinAggregation('min_price', 'resellers.price');
$nestedAggregation = new NestedAggregation('resellers', 'resellers');
$nestedAggregation->addAggregation($minAggregation);

$search = new Search();
$search->addAggregation($nestedAggregation);

$queryArray = $search->toArray();
