[][src]Struct tantivy::query::RangeQuery

pub struct RangeQuery { /* fields omitted */ }

RangeQuery match all documents that have at least one term within a defined range.

Matched document will all get a constant Score of one.

Implementation

The current implement will iterate over the terms within the range and append all of the document cross into a BitSet.

Example

let searcher = reader.searcher();

let docs_in_the_sixties = RangeQuery::new_u64(year_field, 1960..1970);

let num_60s_books = searcher.search(&docs_in_the_sixties, &Count)?;

Methods

impl RangeQuery[src]

pub fn new_term_bounds(
    field: Field,
    value_type: Type,
    left_bound: &Bound<Term>,
    right_bound: &Bound<Term>
) -> RangeQuery
[src]

Creates a new RangeQuery from bounded start and end terms.

If the value type is not correct, something may go terribly wrong when the Weight object is created.

pub fn new_i64(field: Field, range: Range<i64>) -> RangeQuery[src]

Creates a new RangeQuery over a i64 field.

If the field is not of the type i64, tantivy will panic when the Weight object is created.

pub fn new_i64_bounds(
    field: Field,
    left_bound: Bound<i64>,
    right_bound: Bound<i64>
) -> RangeQuery
[src]

Create a new RangeQuery over a i64 field.

The two Bound arguments make it possible to create more complex ranges than semi-inclusive range.

If the field is not of the type i64, tantivy will panic when the Weight object is created.

pub fn new_f64(field: Field, range: Range<f64>) -> RangeQuery[src]

Creates a new RangeQuery over a f64 field.

If the field is not of the type f64, tantivy will panic when the Weight object is created.

pub fn new_f64_bounds(
    field: Field,
    left_bound: Bound<f64>,
    right_bound: Bound<f64>
) -> RangeQuery
[src]

Create a new RangeQuery over a f64 field.

The two Bound arguments make it possible to create more complex ranges than semi-inclusive range.

If the field is not of the type f64, tantivy will panic when the Weight object is created.

pub fn new_u64_bounds(
    field: Field,
    left_bound: Bound<u64>,
    right_bound: Bound<u64>
) -> RangeQuery
[src]

Create a new RangeQuery over a u64 field.

The two Bound arguments make it possible to create more complex ranges than semi-inclusive range.

If the field is not of the type u64, tantivy will panic when the Weight object is created.

pub fn new_u64(field: Field, range: Range<u64>) -> RangeQuery[src]

Create a new RangeQuery over a u64 field.

If the field is not of the type u64, tantivy will panic when the Weight object is created.

pub fn new_str_bounds(
    field: Field,
    left: Bound<&str>,
    right: Bound<&str>
) -> RangeQuery
[src]

Create a new RangeQuery over a Str field.

The two Bound arguments make it possible to create more complex ranges than semi-inclusive range.

If the field is not of the type Str, tantivy will panic when the Weight object is created.

pub fn new_str(field: Field, range: Range<&str>) -> RangeQuery[src]

Create a new RangeQuery over a Str field.

If the field is not of the type Str, tantivy will panic when the Weight object is created.

pub fn field(&self) -> Field[src]

Field to search over

pub fn left_bound(&self) -> Bound<Term>[src]

Lower bound of range

pub fn right_bound(&self) -> Bound<Term>[src]

Upper bound of range
