+Faceted search refers to a way to explore large amounts of data by displaying
+summaries about various partitions of the data and later allowing to narrow
+the navigation to a specific partition.
+
+In Elasticsearch, `facets` are also the name of a feature that allowed to
+compute these summaries. `facets` have been replaced by
+<<search-aggregations, aggregations>> in Elasticsearch 1.0, which are a superset
+of facets.
