Struct QueryParser 

pub struct QueryParser(/* private fields */);

A type for building Query objects from strings

Implementations

impl QueryParser

pub fn add_prefix<T>( &mut self, field: impl AsRef<str>, prefix: impl Into<Option<T>>, )

where T: AsRef<str> + Default,

Add a free-text field term prefix

pub fn add_custom_prefix<T: FieldProcessor + Clone + 'static>( &mut self, field: impl AsRef<str>, field_proc: T, )

Add a free-text field term prefix backed by a custom FieldProcessor

pub fn add_custom_boolean_prefix<T, U>( &mut self, field: impl AsRef<str>, field_proc: T, grouping: impl Into<Option<U>>, )

where T: FieldProcessor + Clone + 'static, U: AsRef<str>,

Register a FieldProcessor for a boolean prefix

pub fn add_boolean_prefix<T, U>( &mut self, field: impl AsRef<str>, prefix: impl Into<Option<T>>, grouping: impl Into<Option<U>>, )

where T: AsRef<str> + Default, U: AsRef<str> + Default,

Add a boolean term prefix, allowing the user to restrict a search with a boolean filter specified in the free text query

pub fn add_rangeprocessor<'g>( &mut self, marker: impl Into<String>, slot: impl Into<Slot>, range_proc: impl RangeProcessor + 'static, is_suffix: bool, can_repeat: bool, grouping: impl Into<Option<&'g str>>, )

Register a RangeProcessor

pub fn set_stemmer(&mut self, stemmer: impl AsRef<Stem>)

Set the Stem to be used with this QueryParser

pub fn set_stemming_strategy( &mut self, strategy: impl Into<QueryParser_stem_strategy>, )

Set the StemStrategy

pub fn set_stopper<T: Stopper + 'static>( &mut self, stopper: impl Into<Option<T>>, )

Set the Stopper to be used with this QueryParser

pub fn parse_query<T>( &mut self, query: impl AsRef<str>, flags: impl Into<Option<QueryParser_feature_flag>>, default_prefix: impl Into<Option<T>>, ) -> Query

where T: AsRef<str> + Default,

Parse the given query text into a Query instance

pub fn stoplist(&self) -> TermIter

Return an iterator over terms omitted from the query as stopwords

pub fn unstem(&self, term: impl AsRef<str>) -> TermIter

Return an iterator over unstemmed forms of the given stemmed query term

Trait Implementations

impl Default for QueryParser

fn default() -> Self

Returns the “default value” for a type.
