Struct elasticsearch_dsl::search::queries::compound::ConstantScoreQuery

pub struct ConstantScoreQuery { /* private fields */ }

Wraps a filter query and returns every matching document with a relevance score equal to the boost parameter value.

To create constant score query:

Query::constant_score(Query::term("test1", 123))
    .boost(3)
    .name("test");

Implementations

impl ConstantScoreQuery

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.

Trait Implementations

impl Clone for ConstantScoreQuery

fn clone(&self) -> ConstantScoreQuery

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for ConstantScoreQuery

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

Formats the value using the given formatter.

impl From<ConstantScoreQuery> for Option<Query>

fn from(q: ConstantScoreQuery) -> Self

Converts to this type from the input type.

impl From<ConstantScoreQuery> for Query

fn from(q: ConstantScoreQuery) -> Self

Converts to this type from the input type.

impl IntoIterator for ConstantScoreQuery

type Item = ConstantScoreQuery

The type of the elements being iterated over.

type IntoIter = IntoIter<<ConstantScoreQuery as IntoIterator>::Item>

Which kind of iterator are we turning this into?

fn into_iter(self) -> Self::IntoIter

impl PartialEq<ConstantScoreQuery> for ConstantScoreQuery

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

impl PartialEq<ConstantScoreQuery> for Query

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

impl PartialEq<Query> for ConstantScoreQuery

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.

impl Serialize for ConstantScoreQuery

fn serialize<S>(&self, serializer: S) -> Result<S::Ok, S::Error>where
    S: Serializer,

Serialize this value into the given Serde serializer.
