Struct PhraseQuery 

pub struct PhraseQuery {
    pub field: Field,
    pub terms: Vec<Vec<u8>>,
    pub slop: u32,
    /* private fields */
}

Phrase query - matches documents containing terms in consecutive positions

Example: “quick brown fox” matches only if all three terms appear consecutively in the document.

Fields

field: Field

terms: Vec<Vec<u8>>

Terms in the phrase, in order

slop: u32

Optional slop (max distance between terms, 0 = exact phrase)

Implementations

impl PhraseQuery

pub fn new(field: Field, terms: Vec<Vec<u8>>) -> Self

Create a new exact phrase query

pub fn text(field: Field, phrase: &str) -> Self

Create from text (splits on whitespace and lowercases)

pub fn with_slop(self, slop: u32) -> Self

Set slop (max distance between terms)

pub fn with_global_stats(self, stats: Arc<GlobalStats>) -> Self

Set global statistics for cross-segment IDF
