Spring data repository Aggregation

Question

I am using Spring data and have a repository with some data about cars.

My interface:

public interface CarRepository extends ElasticsearchRepository<Car, String> {

    public List<Car> findByYear(int year);

    public List<Car> findByYearGreaterThan(int year);

}

How can I create a method to use faceted search (I believe they are called aggregations on Elasticsearch) on my repo?

最后使用ElasticSearchTemplate很容易（因为它访问相同的索引）。
