You can combine multiple supported bucket aggregations (such as `terms` and `range`) in a nested structure, and the star-tree index will optimize these nested aggregations. For more information about nested aggregations, see [Nested aggregations]({{site.url}}{{site.baseurl}}/aggregations/#nested-aggregations).

#### Multi-terms aggregations

A star-tree index optimizes `multi_terms` aggregations when the aggregation fields are defined as dimensions in the star-tree configuration. For more information about multi-terms aggregations, see [Multi-terms aggregations]({{site.url}}{{site.baseurl}}/aggregations/bucket/multi-terms/).
