Struct SearchConfig 

pub struct SearchConfig {
    pub top_k: usize,
    pub ef_search: usize,
    pub pruning_threshold: f32,
    pub rerank_factor: Option<usize>,
}

Fields

top_k: usize

ef_search: usize

pruning_threshold: f32

Maximum distance from query to file centroid edge for a file to be searched. Files where distance(query, centroid) - radius > pruning_threshold are skipped. Set to f32::INFINITY to disable pruning (scan all files).

rerank_factor: Option<usize>

When Some(factor), fetch top_k * factor candidates from the HNSW index and rerank them using exact F32 distances before truncating to top_k. Corrects the approximation error introduced by PQ-compressed HNSW distances. None (default) disables reranking.
