Constant Score Query

A query that wraps another query and simply returns a constant score equal to the query boost for every document in the filter. Maps to Lucene ConstantScoreQuery.

GET /_search
{
    "query": {
        "constant_score" : {
            "filter" : {
                "term" : { "user" : "kimchy"}
            },
            "boost" : 1.2
        }
    }
}

Filter clauses are executed in filter context, meaning that scoring is ignored and clauses are considered for caching.
