Not Filter

A filter that filters out matched documents using a query. This filter is more performant then bool filter. Can be placed within queries that accept a filter.

{
    "filtered" : {
        "query" : {
            "term" : { "name.first" : "shay" }
        },
        "filter" : {
            "not" : {
                "filter" :  {
                    "range" : {
                        "postDate" : {
                            "from" : "2010-03-01",
                            "to" : "2010-04-01"
                        }
                    }
                }
            }
        }
    }
}

Caching

The result of the filter is not cached by default. The _cache can be set to true in order to cache it (tough usually not needed).
