Struct elasticsearch_dsl::search::queries::joining::HasParentQuery

pub struct HasParentQuery { /* fields omitted */ }

Returns child documents joined to a specific parent document. You can use a join field mapping to create parent-child relationships between documents in the same index.

To create has_parent query:

Query::has_parent("parent", Query::term("tag", "elasticsearch"));

Implementations

impl HasParentQuery

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

Indicates whether the relevance score of a matching parent document is aggregated into its child documents. Defaults to false.

If false, Elasticsearch ignores the relevance score of the parent document. Elasticsearch also assigns each child document a relevance score equal to the query’s boost, which defaults to 1.

If true, the relevance score of the matching parent document is aggregated into its child documents’ relevance scores.

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

Indicates whether to ignore an unmapped parent_type and not return any documents instead of an error. Defaults to false.

If false, Elasticsearch returns an error if the parent_type is unmapped.

You can use this parameter to query multiple indices that may not contain the parent_type.

pub fn boost(self, boost: impl TryInto<Boost>) -> Self

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

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.
