Struct elasticsearch_dsl::search::queries::compound::ConstantScoreQuery

pub struct ConstantScoreQuery { /* fields omitted */ }

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

To create constant score query:

Query::constant_score(Query::term("test1", 123))
    .boost(3)
    .name("test");

Implementations

impl ConstantScoreQuery

pub fn boost(self, boost: impl TryInto<Boost>) -> Self

Floating point number used to decrease or increase the relevance scores of a query. Defaults to 1.0.

You can use the boost parameter to adjust relevance scores for searches containing two or more queries.

Boost values are relative to the default value of 1.0. A boost value between 0 and 1.0 decreases the relevance score. A value greater than 1.0 increases the relevance score.

pub fn name(self, name: impl Into<String>) -> Self

You can use named queries to track which queries matched returned documents. If named queries are used, the response includes a matched_queries property for each hit.
