Struct MatchQuery 

pub struct MatchQuery<S = Root> { /* private fields */ }

A match-family clause (match, match_phrase, match_phrase_prefix, match_bool_prefix): the analyzed query value plus whichever options the kind supports, all written under the field as an object. The kind selects the wrapper and which setters are meaningful; unset options are simply omitted.

Implementations

impl<S> MatchQuery<S>

pub fn fuzziness(self, fuzziness: impl Into<String>) -> Self

Edit distance for analyzed terms — "AUTO" or an integer-as-string.

pub fn operator(self, operator: impl Into<String>) -> Self

Combine analyzed terms with "AND" or "OR" (default "OR").

pub fn minimum_should_match(self, value: impl Into<String>) -> Self

How many of the analyzed terms must match (e.g. "75%", "2").

pub fn prefix_length(self, prefix_length: u32) -> Self

Leading characters that must match exactly (fuzzy/prefix matching).

pub fn max_expansions(self, max_expansions: u32) -> Self

Cap on terms a prefix / fuzzy term expands into.

pub fn analyzer(self, analyzer: impl Into<String>) -> Self

Override the search analyzer for this clause.

pub fn slop(self, slop: u32) -> Self

Phrase slop — allowed positional gap (phrase / phrase-prefix).

pub fn zero_terms_query(self, value: impl Into<String>) -> Self

Behavior when analysis yields no terms ("none" or "all").

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

Ignore format errors (e.g. analyzing text for a numeric subfield).

pub fn boost(self, boost: f32) -> Self

Multiply this clause’s relevance score by boost.

pub fn name(self, name: impl Into<String>) -> Self

Tag this clause with _name, surfaced in a hit’s matched_queries.

Trait Implementations

impl<S> AsQuery<S> for MatchQuery<S>

fn into_query(self) -> Option<Query<S>>

The clause this produces, or None to contribute nothing.

fn and(self, other: impl AsQuery<S>) -> Query<S>

where Self: Sized,

self AND other. An absent side is the identity.

fn or(self, other: impl AsQuery<S>) -> Query<S>

where Self: Sized,

self OR other. An absent side is the identity.

fn not(self) -> Query<S>

where Self: Sized,

NOT self (negating an absent clause matches everything).

fn to_value(&self) -> Value

where Self: Sized + Clone,

Render this clause to the OpenSearch query DSL. An absent clause renders as match_all. Handy for tests and debugging.

impl<S: Clone> Clone for MatchQuery<S>

fn clone(&self) -> MatchQuery<S>

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl<S: Debug> Debug for MatchQuery<S>

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

Formats the value using the given formatter.
