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

An instance of a Xapian TermGenerator, which can be used to index text with optional stemming

Implementations

impl TermGenerator

pub fn increase_termpos(&mut self, delta: impl Into<Option<u32>>)

Increase the term position used when indexing index_text

Useful to keep phrases from spanning logically separate regions of text

pub fn index_text<T>( &mut self, text: impl AsRef<str>, increment: impl Into<Option<u32>>, prefix: impl Into<Option<T>>, )

where T: AsRef<str> + Default,

Index some text

The within-document-frequency for the text will be increased by increment (or 1 if None) If provided, the text will be prefixed with prefix

pub fn set_database(&mut self, db: impl AsRef<WritableDatabase>)

Set the currently active database

pub fn set_document(&mut self, doc: impl AsRef<Document>)

Set the currently active document

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

Set the stemmer to be used when indexing text

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

Set the stemming strategy to be used when indexing text

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

Set the stopper to be used when indexing text

pub fn set_stopper_strategy( &mut self, strategy: impl Into<TermGenerator_stop_strategy>, )

Set the stopper strategy to be used when indexing text
