Struct elasticsearch_dsl::search::queries::compound::BoolQuery [−][src]
pub struct BoolQuery { /* fields omitted */ }
Expand description
A query that matches documents matching boolean combinations of other queries. The bool query maps to Lucene BooleanQuery. It is built using one or more boolean clauses, each clause with a typed occurrence.
The bool query takes a more-matches-is-better approach, so the score from each matching must or should clause will be added together to provide the final _score for each document.
To create bool query:
Query::bool()
.must(Query::term("test1", 1))
.must(Query::term("test2", 2))
.should(Query::term("test1", 3))
.should(Query::term("test2", 4))
.filter(Query::term("test1", 5))
.filter(Query::term("test2", 6))
.must_not(Query::term("test1", 7))
.must_not(Query::term("test2", 8))
.minimum_should_match("2")
.boost(1.3)
.name("test");

Implementations
The clause (query) must appear in matching documents and will contribute to the score.
The clause (query) must appear in matching documents and will contribute to the score.
The clause (query) should appear in the matching document.
The clause (query) should appear in the matching document.
The clause (query) must appear in matching documents. However unlike must the score of the query will be ignored. Filter clauses are executed in filter context, meaning that scoring is ignored and clauses are considered for caching.

The clause (query) must not appear in the matching documents.
Clauses are executed in filter context
meaning that scoring is ignored and clauses are considered for caching.
Because scoring is ignored, a score of 0
for all documents is returned.
The clause (query) must not appear in the matching documents.
Clauses are executed in filter context

Because scoring is ignored, a score of 0
for all documents is returned.
You can use the minimum_should_match
parameter to specify the number
or percentage of should clauses returned documents must match.
If the bool
query includes at least one should
clause and no
must
or filter
clauses, the default value is 1
.
Otherwise, the default value is 0
.
For other valid values, see the minimum_should_match parameter.
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.
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.
