Constant Score Query
editConstant Score Query
editA 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"}
},
"boost" : 1.2
}
}
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:
{
"constant_score" : {
"query" : {
"term" : { "user" : "kimchy"}
},
"boost" : 1.2
}
}
