Implementations§

Source §

impl ReciprocalRankFusion

Source

pub fn new(k: f64) -> Self

§Arguments

result_lists - 多个检索结果列表，每个列表包含 (doc_id, score) 元组
top_k - 返回的结果数量

§Returns

融合后的排序结果列表

Source

pub fn fuse_with_weights( &self, result_lists: &[Vec<(String, f64)>], weights: &[f64], top_k: usize, ) -> Vec<(String, f64)>
