Struct tantivy::query::BoostQuery

pub struct BoostQuery { /* fields omitted */ }

BoostQuery is a wrapper over a query used to boost its score.

The document set matched by the BoostQuery is strictly the same as the underlying query. The score of each document, is the score of the underlying query multiplied by the boost factor.
