Nested Aggregation
A special single bucket aggregation that enables aggregating nested documents.
一種特殊的單桶聚合，可聚合嵌套文檔。Reverse nested Aggregation
A special single bucket aggregation that enables aggregating on parent docs from nested documents. Effectively this aggregation can break out of the nested block structure and link to other nested structures or the root document, which allows nesting other aggregations that aren’t part of the nested object in a nested aggregation.The reverse_nested aggregation must be defined inside a nested
aggregation.
一種特殊的單桶聚合，支持從嵌套文檔中聚合父文檔。實際上，這種聚合可以脫離嵌套塊結構，並鏈接到其他嵌套結構或根文檔，這允許嵌套不屬於嵌套聚合中嵌套對象的其他聚合。reverse_nested聚合必須在嵌套聚合中定義。
