Struct Query 

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

A composable query clause in scope S.

Handles produce a Query<S> (User::email().eq(…) → Query<Root>, Order::status().eq(…) → Query<Order>). and/or/not and the crate::Search clauses only combine the same scope; a nested query is lifted to its parent scope through the nested handle.

Implementations

impl<S> Query<S>

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

self AND other, within the same scope.

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

self OR other, within the same scope.

pub fn not(self) -> Query<S>

NOT self.

pub fn boost(self, boost: f32) -> Query<S>

Set boost on this clause. On a bool (an and/or/not result) it becomes the bool’s boost; a leaf clause is wrapped in a bool whose single must is the leaf (prefer the leaf builder’s own boost there).

pub fn min_should_match(self, value: impl Into<MinimumShouldMatch>) -> Query<S>

Set minimum_should_match on a should-group. Use this on an or chain (or Search::min_should_match) so the optional clauses become a real constraint — without it, should beside must/filter only scores. Accepts a count (1) or MinimumShouldMatch::percent / raw. A leaf clause is wrapped as a single should.

pub fn to_value(&self) -> Value

Render to the OpenSearch query DSL.

Trait Implementations

impl<S> AsQuery<S> for Query<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 Query<S>

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

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl<S: Debug> Debug for Query<S>

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

Formats the value using the given formatter.
