Struct elasticsearch_dsl::search::queries::specialized::RankFeatureLogarithmQuery

pub struct RankFeatureLogarithmQuery { /* private fields */ }

Boosts the relevance score of documents based on the numeric value of a rank_feature or rank_features field.

To create a rank feature query:

Query::rank_feature("test");

To apply mathematical functions:

Query::rank_feature("test").saturation();
Query::rank_feature("test").saturation().pivot(2.2);
Query::rank_feature("test").logarithm(3.0);
Query::rank_feature("test").sigmoid(1.0, 2.0);
Query::rank_feature("test").linear();

Implementations

impl RankFeatureLogarithmQuery

pub fn boost<T>(self, boost: T) -> Selfwhere
    T: AsPrimitive<f32>,

Floating point number used to decrease or increase the relevance scores of a query. Defaults to 1.0.

You can use the boost parameter to adjust relevance scores for searches containing two or more queries.

Boost values are relative to the default value of 1.0. A boost value between 0 and 1.0 decreases the relevance score. A value greater than 1.0 increases the relevance score.

pub fn name<S>(self, name: S) -> Selfwhere
    S: ToString,

You can use named queries to track which queries matched returned documents. If named queries are used, the response includes a matched_queries property for each hit.

impl PartialEq<Query> for RankFeatureLogarithmQuery

fn eq(&self, other: &Query) -> 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.
