Struct elasticsearch_dsl::search::queries::full_text::CombinedFieldsQuery

pub struct CombinedFieldsQuery { /* private fields */ }

The combined_fields query supports searching multiple text fields as if their contents had been indexed into one combined field. The query takes a term-centric view of the input string: first it analyzes the query string into individual terms, then looks for each term in any of the fields. This query is particularly useful when a match could span multiple text fields.

To create a combined fields query with:

Query::combined_fields(["title", "abstract", "body"], "database systems")
    .boost(2)
    .name("test");

Implementations

impl CombinedFieldsQuery

pub fn auto_generate_synonyms_phrase_query(
    self,
    auto_generate_synonyms_phrase_query: bool
) -> Self

If true, match phrase queries are automatically created for multi-term synonyms. Defaults to true.

See Use synonyms with match query for an example.

pub fn operator(self, operator: Operator) -> Self

Boolean logic used to interpret text in the query value

pub fn minimum_should_match<T>(self, minimum_should_match: T) -> Selfwhere
    T: ToString,

Minimum number of clauses that must match for a document to be returned. See the minimum_should_match parameter for valid values and more information.

pub fn zero_terms_query(self, zero_terms_query: ZeroTermsQuery) -> Self

Indicates whether no documents are returned if the analyzer removes all tokens, such as when using a stop filter.

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 CombinedFieldsQuery

fn clone(&self) -> CombinedFieldsQuery

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for CombinedFieldsQuery

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

Formats the value using the given formatter.

impl Default for CombinedFieldsQuery

fn default() -> CombinedFieldsQuery

Returns the “default value” for a type.

impl From<CombinedFieldsQuery> for Option<Query>

fn from(q: CombinedFieldsQuery) -> Self

Converts to this type from the input type.

impl From<CombinedFieldsQuery> for Query

fn from(q: CombinedFieldsQuery) -> Self

Converts to this type from the input type.

impl IntoIterator for CombinedFieldsQuery

type Item = CombinedFieldsQuery

The type of the elements being iterated over.

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

Which kind of iterator are we turning this into?

impl PartialEq<CombinedFieldsQuery> for CombinedFieldsQuery

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

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

const 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.

const 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 CombinedFieldsQuery

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

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

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

impl Serialize for CombinedFieldsQuery

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