=== Constant Score Query
|
||
|
|
|
||
|
|
A query that wraps a filter or another query and simply returns a
|
||
|
|
constant score equal to the query boost for every document in the
|
||
|
|
filter. Maps to Lucene `ConstantScoreQuery`.

"constant_score" : {
|
||
|
|
"filter" : {
|
||
|
|
"term" : { "user" : "kimchy"}
|
||

|
},

The filter object can hold only filter elements, not queries. Filters
|
||
|
|
can be much faster compared to queries since they don't perform any
|
||
|
|
scoring, especially when they are cached.
|
||
|
|
|
||
|
|
A query can also be wrapped in a `constant_score` query:

"query" : {

"term" : { "user" : "kimchy"}
|

},

"boost" : 1.2

}
