Struct FullTextBoost

pub struct FullTextBoost {
    pub boost_factor: f64,
    pub phrase: String,
}

FullTextBoost : Boost phrase is useful for when you want to boost certain phrases in the fulltext (SPLADE) and BM25 search results. I.e. making sure that the listing for AirBNB itself ranks higher than companies who make software for AirBNB hosts by boosting the in-document-frequency of the AirBNB token (AKA word) for its official listing. Conceptually it multiples the in-document-importance second value in the tuples of the SPLADE or BM25 sparse vector of the chunk_html innerText for all tokens present in the boost phrase by the boost factor like so: (token, in-document-importance) -> (token, in-document-importance*boost_factor).

Fields

boost_factor: f64

Amount to multiplicatevly increase the frequency of the tokens in the phrase by

phrase: String

The phrase to boost in the fulltext document frequency index

Trait Implementations

impl Clone for FullTextBoost

fn clone(&self) -> FullTextBoost

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for FullTextBoost

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

Formats the value using the given formatter.

impl Default for FullTextBoost

fn default() -> FullTextBoost

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for FullTextBoost

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl PartialEq for FullTextBoost

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

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

where __S: Serializer,

Serialize this value into the given Serde serializer.
