# Bucket aggregations
|
||
|
|
|
||
|
|
Bucket aggregations categorize sets of documents as buckets. The type of bucket aggregation determines whether a given document falls into a bucket or not.
|
||
|
|
|

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