Constant score query [query-dsl-constant-score-query]

Wraps a filter query and returns every matching document with a relevance score equal to the boost parameter value.

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

Top-level parameters for constant_score [constant-score-top-level-params]

filter
(Required, query object) Filter query you wish to run. Any returned documents must match this query.

Filter queries do not calculate relevance scores. To speed up performance, {{es}} automatically caches frequently used filter queries.

boost
(Optional, float) Floating point number used as the constant relevance score for every document matching the filter query. Defaults to 1.0.
