Bucket aggregations

Bucket aggregations categorize sets of documents as buckets. The type of bucket aggregation determines the bucket for a given document.

You can use bucket aggregations to implement faceted navigation (usually placed as a sidebar on a search result landing page) to help your users filter the results.
