Filter Facets

edit

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

The equivalent aggregation would be the filter aggregation.

A filter facet (not to be confused with a facet filter) allows you to return a count of the hits matching the filter. The filter itself can be expressed using the Query DSL. For example:

{
    "facets" : {
        "wow_facet" : {
            "filter" : {
                "term" : { "tag" : "wow" }
            }
        }
    }
}

Note, filter facet filters are faster than query facet when using native filters (non query wrapper ones).
