pub struct BoostingQuery { /* private fields */ }
Expand description
Returns documents matching a positive
query while reducing the
relevance score
of documents that also match a negative
query.
You can use the boosting
query to demote certain documents without excluding them from the search results.
To create boosting query:
Query::boosting(Query::term("test1", 123), Query::term("test2", 456), 0.2)
.boost(3)
.name("test");

pub fn boost<T>(self, boost: T) -> Selfwhere
T: AsPrimitive<f32>,
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.
