Struct elasticsearch_dsl::search::queries::full_text::MatchPhrasePrefixQuery

pub struct MatchPhrasePrefixQuery { /* private fields */ }

Returns documents that contain the words of a provided text, in the same order as provided. The last term of the provided text is treated as a prefix, matching any words that begin with that term.

To create a MatchPhrasePrefix query:

Query::match_phrase_prefix("test", "search text")
    .boost(2)
    .name("test");

Implementations

impl MatchPhrasePrefixQuery

pub fn analyzer<T>(self, analyzer: T) -> Self where
    T: ToString, 

Analyzer used to convert the text in the query value into tokens. Defaults to the index-time analyzer mapped for the <field>. If no analyzer is mapped, the index’s default analyzer is used.

pub fn max_expansions(self, max_expansions: u8) -> Self

Maximum number of terms to which the query will expand. Defaults to 50.

pub fn slop(self, slop: u8) -> Self

The maximum number of intervening unmatched positions, as well as whether matches are required to be in-order.

pub fn zero_terms_query(self, zero_terms_query: ZeroTermsQuery) -> Self

Indicates whether no documents are returned if the analyzer removes all tokens, such as when using a stop filter.

pub fn boost<T>(self, boost: T) -> Self where
    T: AsPrimitive<f32>, 

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<S>(self, name: S) -> Self where
    S: ToString, 

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.
