Struct SearchParams 

pub struct SearchParams {
    pub top_k: usize,
    pub n_probe: usize,
    pub n_candidate_docs: Option<usize>,
    pub centroid_score_threshold: Option<f32>,
}

Tunable knobs for a single search call.

Fields

top_k: usize

Number of top-scoring documents to return.

n_probe: usize

Number of top dot-product centroids each query token probes.

n_candidate_docs: Option<usize>

Maximum number of candidates surviving PLAID’s centroid-interaction stage that proceed to full decode + exact MaxSim. None disables centroid interaction and sends every probed candidate straight to decode — correct but slower for large corpora.

centroid_score_threshold: Option<f32>

Minimum per-centroid score (max dot product against any query token) required for a centroid to contribute to candidate generation and centroid interaction. Centroids below this threshold are treated as unreachable for this query. None disables pruning, matching the legacy probe behaviour.
