Query Facetsedit

Facets are deprecated and will be removed in a future release. You are encouraged to migrate to aggregations instead.

There is no equivalent aggregation but you can use the
filter
aggregation and wrap
the query inside a 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:
{ "facets" : { "wow_facet" : { "query" : { "term" : { "tag" : "wow" } } } } }
