pub fn build_index(&mut self)

Build a VP-tree index from the current gallery for fast nearest-neighbor search.

pub fn search_indexed( &self, embedding: &Tensor, k: usize, ) -> Result<Vec<Recognition>, RecognizeError>

Search using the VP-tree index if available, otherwise fall back to linear scan.

Returns the k nearest identities that meet the recognition threshold.
