##List of supported aggregations

Plastic doesn't support all available aggregations yet like the nested aggregation however you can still implement this functionality.
Knowing that Plastic uses
ongr-io/ElasticsearchDSL to build the queries we can do the following.
Post::search()->aggregate(function($builder){
$minAggregation = new MinAggregation('min_price', 'resellers.price');
$nestedAggregation = new NestedAggregation('resellers', 'resellers');
$nestedAggregation->addAggregation($minAggregation);
$builder->append($nestedAggregation);
});
