Nested aggregation #

A single-bucket aggregation that scopes its sub-aggregations to a nested object path. Nested field values are addressable as dotted columns, so sub-aggregations read variants.color style fields directly.

reverse_nested (only valid inside a nested aggregation) jumps back out to the parent-document scope.

Example #

Products carry a variants array; aggregate one value per parent product inside the nested scope, then reverse back out:

Parameters for nested #

• path
  (Required, string) Path of the nested object (dotted).
• aggs
  (Optional, object) Sub-aggregations in nested scope.

Parameters for reverse_nested #

• aggs
  (Optional, object) Sub-aggregations back in the parent scope.
