Struct KnnQuery

pub struct KnnQuery {
    pub field: String,
    pub query_vector: Vec<f32>,
    pub k: usize,
    pub num_candidates: usize,
    pub threshold: Option<f32>,
}

Expand description

Approximate k-nearest-neighbor query on a dense_vector field.

See [[feature-knn-query-type]].

Fields§

§field: String§query_vector: Vec<f32>§k: usize§num_candidates: usize§threshold: Option<f32>

Minimum score threshold. Results with score < threshold are excluded. Score is metric-specific (see crate::vector::distance_to_score).
