Struct StopFilter

Source

pub struct StopFilter { /* private fields */ }

Expand description

Removes stop words from the token stream.

Stop words are common words (like “the”, “is”, “at”) that carry little meaning for search. Removing them reduces index size and can improve precision. Positions are preserved so phrase queries still work correctly.

See [[analyzers#Token Filters]].

Implementations§

Source §

impl StopFilter

Source

pub fn new(words: impl IntoIterator<Item = impl Into<String>>) -> Self

Create a stop filter with a custom set of stop words.

Source

pub fn english() -> Self

Create a stop filter with the default English stop words.

Uses the same list as Lucene’s EnglishAnalyzer.
