Struct elasticsearch_dsl::search::queries::term_level::RegexpQuery

pub struct RegexpQuery { /* fields omitted */ }

Returns documents that contain terms matching a regular expression.

A regular expression is a way to match patterns in data using placeholder characters, called operators. For a list of operators supported by the regexp query, see Regular expression syntax.

To create a regexp query:

Query::regexp("test", "username");

Implementations

impl RegexpQuery

pub fn flags<I>(self, flags: I) -> Self where
    I: IntoIterator<Item = RegexpFlag>, 

Enables optional operators for the regular expression. For valid values and more information, see Regular expression syntax.

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

Allows case insensitive matching of the regular expression 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 max_determinized_states(self, max_determinized_states: u64) -> Self

Maximum number of automaton states required for the query. Default is 10000.

Elasticsearch uses Apache Lucene internally to parse regular expressions. Lucene converts each regular expression to a finite automaton containing a number of determinized states.

You can use this parameter to prevent that conversion from unintentionally consuming too many resources. You may need to increase this limit to run complex regular expressions.

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 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.
