Struct AcornSearchParamsBuilder 

pub struct AcornSearchParamsBuilder { /* private fields */ }

Implementations

impl AcornSearchParamsBuilder

pub fn new(enable: bool) -> Self

Create a new AcornSearchParamsBuilder with required enable parameter.

Arguments

• enable - If true, ACORN may be used for HNSW search based on filter selectivity

Examples

use qdrant_client::qdrant::AcornSearchParamsBuilder;

let acorn = AcornSearchParamsBuilder::new(true).build();
let acorn_with_selectivity = AcornSearchParamsBuilder::new(true)
    .max_selectivity(0.5)
    .build();

pub fn max_selectivity(self, value: f64) -> Self

Set maximum selectivity threshold for enabling ACORN.

If estimated filter selectivity is higher than this value, ACORN will not be used. Selectivity is estimated as: estimated number of points satisfying the filters / total number of points

Value between 0.0 (never) and 1.0 (always). Default is 0.4.

pub fn build(self) -> AcornSearchParams
