Struct google_api_proto::google::cloud::discoveryengine::v1alpha::search_request::boost_spec::ConditionBoostSpec

pub struct ConditionBoostSpec {
    pub condition: String,
    pub boost: f32,
    pub boost_control_spec: Option<BoostControlSpec>,
}

Boost applies to documents which match a condition.

Fields

condition: String

An expression which specifies a boost condition. The syntax and supported fields are the same as a filter expression. See [SearchRequest.filter][google.cloud.discoveryengine.v1alpha.SearchRequest.filter] for detail syntax and limitations.

Examples:

• To boost documents with document ID “doc_1” or “doc_2”, and color “Red” or “Blue”: (document_id: ANY("doc_1", "doc_2")) AND (color: ANY("Red", "Blue"))

boost: f32

Strength of the condition boost, which should be in [-1, 1]. Negative boost means demotion. Default is 0.0.

Setting to 1.0 gives the document a big promotion. However, it does not necessarily mean that the boosted document will be the top result at all times, nor that other documents will be excluded. Results could still be shown even when none of them matches the condition. And results that are significantly more relevant to the search query can still trump your heavily favored but irrelevant documents.

Setting to -1.0 gives the document a big demotion. However, results that are deeply relevant might still be shown. The document will have an upstream battle to get a fairly high ranking, but it is not blocked out completely.

Setting to 0.0 means no boost applied. The boosting condition is ignored. Only one of the (condition, boost) combination or the boost_control_spec below are set. If both are set then the global boost is ignored and the more fine-grained boost_control_spec is applied.

boost_control_spec: Option<BoostControlSpec>

Complex specification for custom ranking based on customer defined attribute value.

Trait Implementations

impl Clone for ConditionBoostSpec

fn clone(&self) -> ConditionBoostSpec

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for ConditionBoostSpec

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

Formats the value using the given formatter.

impl Default for ConditionBoostSpec

fn default() -> Self

Returns the “default value” for a type.

impl Message for ConditionBoostSpec

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 ConditionBoostSpec

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

This method tests for self and other values to be equal, and is used by ==.

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

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