Struct AcornSearchParams 

pub struct AcornSearchParams {
    pub enable: bool,
    pub max_selectivity: Option<OrderedFloat<f64>>,
}

ACORN-related search parameters

Fields

enable: bool

If true, then ACORN may be used for the HNSW search based on filters selectivity. Improves search recall for searches with multiple low-selectivity payload filters, at cost of performance.

max_selectivity: Option<OrderedFloat<f64>>

Maximum selectivity of filters to enable ACORN.

If estimated filters 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.

0.0 for never, 1.0 for always. Default is 0.4.

Trait Implementations

impl Clone for AcornSearchParams

fn clone(&self) -> AcornSearchParams

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for AcornSearchParams

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Default for AcornSearchParams

fn default() -> AcornSearchParams

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for AcornSearchParams

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Hash for AcornSearchParams

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl JsonSchema for AcornSearchParams

fn schema_name() -> String

The name of the generated JSON Schema.

fn schema_id() -> Cow<'static, str>

Returns a string that uniquely identifies the schema produced by this type.

fn json_schema(generator: &mut SchemaGenerator) -> Schema

Generates a JSON Schema for this type.

fn is_referenceable() -> bool

Whether JSON Schemas generated for this type should be re-used where possible using the $ref keyword.

impl PartialEq for AcornSearchParams

fn eq(&self, other: &AcornSearchParams) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl Serialize for AcornSearchParams

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.

impl Validate for AcornSearchParams

fn validate(&self) -> Result<(), ValidationErrors>

impl<'v_a> ValidateArgs<'v_a> for AcornSearchParams

type Args = ()

fn validate_with_args(&self, args: Self::Args) -> Result<(), ValidationErrors>

impl Copy for AcornSearchParams

impl StructuralPartialEq for AcornSearchParams
