Struct tantivy::query::RequiredOptionalScorer
source · pub struct RequiredOptionalScorer<TReqScorer, TOptScorer, TScoreCombiner: ScoreCombiner> { /* private fields */ }
Expand description
Given a required scorer and an optional scorer matches all document from the required scorer and complements the score using the optional scorer.
This is useful for queries like +somethingrequired somethingoptional
.
Note that somethingoptional
has no impact on the DocSet
.
