Struct LexicalQuery 

pub struct LexicalQuery {
    pub groups: Vec<Vec<String>>,
}

OR-ed groups of tokens. All tokens of a group must occur in one field, without requiring adjacency or source order; plain words are groups of one.

Fields

groups: Vec<Vec<String>>

Implementations

impl LexicalQuery

pub fn new<'a>(queries: impl IntoIterator<Item = &'a str>) -> Self

Build from one or more phrasings. Whitespace separates groups; within a group, punctuation joins tokens into a conjunction. Single-token stopwords are dropped, so a question matches on its content words.

pub fn is_empty(&self) -> bool

pub fn fts5(&self) -> Option<String>

An FTS5 MATCH expression: quoted tokens AND-ed within each field, groups OR-ed. Only our fixed field names are parsed as FTS syntax.
