Struct Bm25CorpusStats 

pub struct Bm25CorpusStats {
    pub n: u32,
    pub avgdl: f64,
    pub df: BTreeMap<String, u32>,
    pub dl: BTreeMap<String, u32>,
}

Persisted corpus-wide BM25 statistics (Ripwire warm lexindex). IDF and average length come from the full indexed corpus, not the candidate slice. Stored in store meta (bm25_corpus), never on FILE entity attributes.

Fields

n: u32

avgdl: f64

df: BTreeMap<String, u32>

Term → document frequency (docs containing the term at least once).

dl: BTreeMap<String, u32>

Document id → weighted length.

Implementations

impl Bm25CorpusStats

pub fn from_docs(docs: &[LexDoc]) -> Self

Build corpus-wide stats. Document order does not affect df/dl maps; n is docs.len().
