Implementations

impl InvertedIndex

pub fn new() -> Self

pub fn index_document(&mut self, doc_id: &str, text: &str)

Index a document’s text content.

pub fn remove_document(&mut self, doc_id: &str)

Remove a document from the index.

pub fn search( &self, query: &str, top_k: usize, mode: QueryMode, params: Bm25Params, ) -> Vec<TextSearchResult>

Search with BM25 scoring.

Returns results sorted by descending score, limited to top_k.

pub fn search_fuzzy( &self, query: &str, max_distance: usize, top_k: usize, params: Bm25Params, ) -> Vec<TextSearchResult>

Fuzzy search: find documents matching query terms within Levenshtein distance.

pub fn doc_count(&self) -> u32

pub fn token_count(&self) -> usize
