HNSW index configuration

Fields

m: usize

Maximum number of bi-directional links per node per layer (M) Higher values improve recall but increase memory and search time Typical range: 8-64, default: 16

m_max_0: usize

Maximum connections for layer 0 (typically M * 2)

ef_construction: usize

Size of dynamic candidate list during construction (ef_construction) Higher values improve graph quality but slow construction Typical range: 100-500, default: 200

ef_search: usize

Size of dynamic candidate list during search (ef_search) Higher values improve recall but slow search Typical range: 50-200, default: 50

ml: f64

Layer generation probability parameter (ml) 1/ln(ml) determines layer assignment probability Default: 1.0 / ln(m) ≈ 0.36 for m=16

dimension: usize

Vector dimension (must be consistent)

metric: DistanceMetric

Distance metric
