Struct tantivy::query::BooleanQuery

pub struct BooleanQuery { /* fields omitted */ }

The boolean query combines a set of queries

The documents matched by the boolean query are those which

• match all of the sub queries associated with the Must occurence
• match none of the sub queries associated with the MustNot occurence.
• match at least one of the subqueries that is not a MustNot occurence.

Methods

impl BooleanQuery

pub fn new_multiterms_query(terms: Vec<Term>) -> BooleanQuery

Helper method to create a boolean query matching a given list of terms. The resulting query is a disjunction of the terms.

pub fn clauses(&self) -> &[(Occur, Box<dyn Query>)]

Deconstructed view of the clauses making up this query.
