Struct tantivy::query::PhraseQuery
source · [−]pub struct PhraseQuery { /* private fields */ }
Expand description
PhraseQuery
matches a specific sequence of words.
For instance the phrase query for "part time"
will match
the sentence
Alan just got a part time job.
On the other hand it will not match the sentence.
This is my favorite part of the job.
Using a PhraseQuery
on a field requires positions
to be indexed for this field.
Implementations
sourceimpl PhraseQuery
impl PhraseQuery
sourcepub fn new(terms: Vec<Term>) -> PhraseQuery
pub fn new(terms: Vec<Term>) -> PhraseQuery
Creates a new PhraseQuery
given a list of terms.
There must be at least two terms, and all terms must belong to the same field. Offset for each term will be same as index in the Vector
sourcepub fn new_with_offset(terms: Vec<(usize, Term)>) -> PhraseQuery
pub fn new_with_offset(terms: Vec<(usize, Term)>) -> PhraseQuery
Creates a new PhraseQuery
given a list of terms and their offsets.
Can be used to provide custom offset for each term.
