+# 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.
+

+# Metric aggregations
+
+Metric aggregations let you perform simple calculations such as finding the minimum, maximum, and average values of a field.
+
+## Types of metric aggregations
+
+There are two types of metric aggregations: single-value metric aggregations and multi-value metric aggregations.
+
+### Single-value metric aggregations
+
+Single-value metric aggregations return a single metric, for example, `sum`, `min`, `max`, `avg`, `cardinality`, or `value_count`.
+
+### Multi-value metric aggregations
+
+Multi-value metric aggregations return more than one metric. These include `stats`, `extended_stats`, `matrix_stats`, `percentile`, `percentile_ranks`, `geo_bound`, `top_hits`, and `scripted_metric`.
+
+## Supported metric aggregations
+
+OpenSearch supports the following metric aggregations:
+
+- [Average]({{site.url}}{{site.baseurl}}/aggregations/metric/average/)
+- [Cardinality]({{site.url}}{{site.baseurl}}/aggregations/metric/cardinality/)
+- [Extended stats]({{site.url}}{{site.baseurl}}/aggregations/metric/extended-stats/)

+- [Maximum]({{site.url}}{{site.baseurl}}/aggregations/metric/maximum/)
+- [Minimum]({{site.url}}{{site.baseurl}}/aggregations/metric/minimum/)
+- [Percentile ranks]({{site.url}}{{site.baseurl}}/aggregations/metric/percentile-ranks/)
