Struct AnnConfig 

pub struct AnnConfig {
    pub m: usize,
    pub ef_construction: usize,
    pub ef_search: usize,
    pub max_results: usize,
    pub enabled: bool,
    pub min_vectors_for_ann: usize,
}

Configuration for ANN index construction.

Fields

m: usize

Number of neighbors per node (higher = better recall, slower build). Default: 16

ef_construction: usize

Size of dynamic candidate list during construction (higher = better recall, slower build). Default: 200

ef_search: usize

Size of dynamic candidate list during search (higher = better recall, slower search). Default: 50

max_results: usize

Maximum number of results to return from ANN search. Default: 100

enabled: bool

Whether to use ANN or fall back to linear scan. Default: true (use ANN when beneficial)

min_vectors_for_ann: usize

Minimum number of vectors before ANN is used. Below this threshold, linear scan is used even if enabled=true. Default: 1000
