Struct QuantizationSearchParams

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

Fields

ignore: Option<bool>

If set to true, search will ignore quantized vector data

rescore: Option<bool>

If true, use original vectors to re-score top-k results. If ignored, qdrant decides automatically does rescore enabled or not.

oversampling: Option<f64>

Oversampling factor for quantization.

Defines how many extra vectors should be pre-selected 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 pre-selected using quantized index, and then top-100 will be returned after re-scoring.

Implementations

impl QuantizationSearchParams

pub fn ignore(&self) -> bool

Returns the value of ignore, or the default value if ignore is unset.

pub fn rescore(&self) -> bool

Returns the value of rescore, or the default value if rescore is unset.

pub fn oversampling(&self) -> f64

Returns the value of oversampling, or the default value if oversampling is unset.

Trait Implementations

impl Clone for QuantizationSearchParams

fn clone(&self) -> QuantizationSearchParams

Returns a copy 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() -> Self

Returns the “default value” for a type.

impl From<QuantizationSearchParamsBuilder> for QuantizationSearchParams

fn from(value: QuantizationSearchParamsBuilder) -> Self

Converts to this type from the input type.

impl Message for QuantizationSearchParams

fn encoded_len(&self) -> usize

Returns the encoded length of the message without a length delimiter.

fn clear(&mut self)

Clears the message, resetting all fields to their default.

fn encode(&self, buf: &mut impl BufMut) -> Result<(), EncodeError>

where Self: Sized,

Encodes the message to a buffer.

fn encode_to_vec(&self) -> Vec<u8>

where Self: Sized,

Encodes the message to a newly allocated buffer.

fn encode_length_delimited( &self, buf: &mut impl BufMut, ) -> Result<(), EncodeError>

where Self: Sized,

Encodes the message with a length-delimiter to a buffer.

fn encode_length_delimited_to_vec(&self) -> Vec<u8>

where Self: Sized,

Encodes the message with a length-delimiter to a newly allocated buffer.

fn decode(buf: impl Buf) -> Result<Self, DecodeError>

where Self: Default,

Decodes an instance of the message from a buffer.

fn decode_length_delimited(buf: impl Buf) -> Result<Self, DecodeError>

where Self: Default,

Decodes a length-delimited instance of the message from the buffer.

fn merge(&mut self, buf: impl Buf) -> Result<(), DecodeError>

where Self: Sized,

Decodes an instance of the message from a buffer, and merges it into self.

fn merge_length_delimited(&mut self, buf: impl Buf) -> Result<(), DecodeError>

where Self: Sized,

Decodes a length-delimited instance of the message from buffer, and merges it into self.

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.
