Implementations

impl Bm25Index

pub fn to_bytes(&self) -> Vec<u8>

Encode for storage in section 0x08 (v2).

pub fn from_bytes(bytes: &[u8]) -> Result<Self, RuntimeError>

impl Bm25Index

pub fn build(docs: &[String], k1: f32, b: f32) -> Self

Build a BM25 index from the canonical chunk texts.

pub fn search(&self, query_text: &str, k: usize) -> Vec<(usize, f32)>

Score query_text against the corpus, return the top-k (doc, score) pairs. Empty query returns an empty vec.
