Hello Team,
Is there any **_Java client API documentation_** which explains the usage of Composite Aggregation like other aggregations([https://www.elastic.co/guide/en/elasticsearch/client/java-api/current/\_bucket\_aggregations.html](https://www.elastic.co/guide/en/elasticsearch/client/java-api/current/_bucket_aggregations.html)).
