Enum SearchQuality 

pub enum SearchQuality {
    Fast,
    Balanced,
    Accurate,
    Perfect,
    Custom {
        ef: u32,
    },
    Adaptive {
        min_ef: u32,
        max_ef: u32,
    },
    AutoTune,
}

Search quality profile controlling the recall/latency tradeoff.

Maps to core velesdb_core::SearchQuality. In HNSW-backed collections, this controls the ef_search parameter. Higher quality means better recall at the cost of increased latency.

Variants

Fast

Fast search (ef_search=96). ~95% recall, lowest latency.

Balanced

Balanced search (ef_search=160). ~99.5% recall, production default.

Accurate

Accurate search (ef_search=512). ~100% recall.

Perfect

Perfect recall mode (ef_search=4096). Guaranteed 100% recall.

Custom

Custom ef_search value for fine-grained control.

Fields

ef: u32

The ef_search expansion factor.

Adaptive

Adaptive two-phase search that starts low and doubles if needed.

Fields

min_ef: u32

Minimum ef_search (starting point).

max_ef: u32

Maximum ef_search (cap).

AutoTune

Auto-tuned adaptive search based on collection statistics.
