Struct FilteredSearchConfig 

pub struct FilteredSearchConfig {
    pub min_ef_search: usize,
    pub max_ef_search: usize,
    pub ef_multiplier: f32,
}

Configuration for filtered search operations.

Fields

min_ef_search: usize

The minimum ef_search to use when filtering. When filters are selective, ef_search may need to be increased to maintain recall.

max_ef_search: usize

The maximum ef_search to use when filtering.

ef_multiplier: f32

The ef_search multiplier to apply when filtering. When a filter is applied, ef_search is multiplied by this factor to account for nodes that may be filtered out during traversal.

Implementations

impl FilteredSearchConfig

pub const fn new() -> Self

Create a new filtered search configuration.

pub const fn with_min_ef_search(self, min_ef: usize) -> Self

Set the minimum ef_search.

pub const fn with_max_ef_search(self, max_ef: usize) -> Self

Set the maximum ef_search.

pub const fn with_ef_multiplier(self, multiplier: f32) -> Self

Set the ef_search multiplier.

pub fn adjusted_ef(&self, base_ef: usize, selectivity: Option<f32>) -> usize

Calculate the adjusted ef_search based on filter selectivity.

Arguments

• base_ef - The base ef_search value
• selectivity - Optional estimated filter selectivity (0.0 to 1.0). 1.0 means all nodes pass, 0.0 means no nodes pass. If None, the default multiplier is applied.
