Struct elasticsearch_dsl::search::queries::full_text::MatchPhrasePrefixQuery
source · pub struct MatchPhrasePrefixQuery { /* private fields */ }
Expand description
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");

sourcepub fn analyzer<T>(self, analyzer: T) -> Selfwhere
T: ToString,
pub fn analyzer<T>(self, analyzer: T) -> Selfwhere 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.
sourcepub fn max_expansions(self, max_expansions: u8) -> Self
pub fn max_expansions(self, max_expansions: u8) -> Self
Maximum number of terms to which the query will expand.
Defaults to 50
.
sourcepub fn slop(self, slop: u8) -> Self
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.
sourcepub fn zero_terms_query(self, zero_terms_query: ZeroTermsQuery) -> Self
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.
sourcepub fn boost<T>(self, boost: T) -> Selfwhere
T: AsPrimitive<f32>,
pub fn boost<T>(self, boost: T) -> Selfwhere 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.
