Struct QuantizationSearchParams 

pub struct QuantizationSearchParams {
    pub ignore: bool,
    pub rescore: Option<bool>,
    pub oversampling: Option<f64>,
}

Additional parameters of the search

Fields

ignore: bool

If true, quantized vectors are ignored. Default is false.

rescore: Option<bool>

If true, use original vectors to re-score top-k results. Might require more time in case if original vectors are stored on disk. If not set, qdrant decides automatically apply rescoring or not.

oversampling: Option<f64>

Oversampling factor for quantization. Default is 1.0.

Defines how many extra vectors should be preselected using quantized index, and then re-scored using original vectors.

For example, if oversampling is 2.4 and limit is 100, then 240 vectors will be preselected using quantized index, and then top-100 will be returned after re-scoring.

Trait Implementations

impl Clone for QuantizationSearchParams

fn clone(&self) -> QuantizationSearchParams

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for QuantizationSearchParams

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

Formats the value using the given formatter.

impl Default for QuantizationSearchParams

fn default() -> QuantizationSearchParams

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for QuantizationSearchParams

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Hash for QuantizationSearchParams

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 QuantizationSearchParams

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 QuantizationSearchParams

fn eq(&self, other: &QuantizationSearchParams) -> 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 QuantizationSearchParams

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 QuantizationSearchParams

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

impl<'v_a> ValidateArgs<'v_a> for QuantizationSearchParams

type Args = ()

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

impl Copy for QuantizationSearchParams

impl StructuralPartialEq for QuantizationSearchParams
