# Constant score query [query-dsl-constant-score-query]
|
||
|
|
|
||
|
|
|
||
|
|
Wraps a [filter query](/reference/query-languages/query-dsl/query-dsl-bool-query.md) and returns every matching document with a [relevance score](/reference/query-languages/query-dsl/query-filter-context.md#relevance-scores) equal to the `boost` parameter value.

|
||
|

```console
|
||
|
|
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](/reference/query-languages/query-dsl/query-dsl-bool-query.md) you wish to run. Any returned documents must match this query.
|
||
|
|
|
||
|
|
Filter queries do not calculate [relevance scores](/reference/query-languages/query-dsl/query-filter-context.md#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](/reference/query-languages/query-dsl/query-filter-context.md#relevance-scores) for every document matching the `filter` query. Defaults to `1.0`.
