Struct elasticsearch_dsl::search::queries::term_level::PrefixQuery

pub struct PrefixQuery { /* fields omitted */ }

Returns documents that contain a specific prefix in a provided field.

To create a prefix query with numeric values:

Query::prefix("test", 123);

To create a prefix query with string values and optional fields:

Query::prefix("test", "username")
    .boost(2)
    .name("test");

Implementations

impl PrefixQuery

pub fn rewrite(self, rewrite: Rewrite) -> Self

Method used to rewrite the query. For valid values and more information, see the rewrite parameter.

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

Allows ASCII case insensitive matching of the value with the indexed field values when set to true. Default is false which means the case sensitivity of matching depends on the underlying field’s mapping.

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.
