=== Query Facets

include::deprecated.asciidoc[]

NOTE: There is no equivalent aggregation but you can use the
<<search-aggregations-bucket-filter-aggregation,`filter`>> aggregation and wrap
the query inside a <<query-dsl-query-filter,query filter>>.

A facet query allows to return a count of the hits matching the facet
query. The query itself can be expressed using the Query DSL. For
example:

[source,js]
--------------------------------------------------
{
    "facets" : {
        "wow_facet" : {
            "query" : {
                "term" : { "tag" : "wow" }
            }
        }
    }
}
