Struct Bm25Params 

pub struct Bm25Params {
    pub k1: f32,
    pub b: f32,
}

BM25 ranking parameters.

Controls how term frequency and document length affect scoring. The defaults (k1 = 1.2, b = 0.75) are standard Okapi BM25 values that work well across most corpora.

Fields

k1: f32

Term frequency saturation factor. Higher values give more weight to repeated terms. Range: 0.5–3.0. Default: 1.2.

b: f32

Length normalization factor. 0.0 = no length normalization, 1.0 = full normalization. Default: 0.75.
