Struct tantivy::Document

pub struct Document { /* fields omitted */ }

Tantivy’s Document is the object that can be indexed and then searched for.

Documents are fundamentally a collection of unordered couple (field, value). In this list, one field may appear more than once.

Documents are really just a list of couple (field, value). In this list, one field may appear more than once.

Implementations

impl Document

pub fn is_empty(&self) -> bool

Returns true iff the document contains no fields.

pub fn filter_fields<P: Fn(Field) -> bool>(&mut self, predicate: P)

Retain only the field that are matching the predicate given in argument.

    Facet: From<F>, 

Adding a facet to the document.

pub fn add_text<S: ToString>(&mut self, field: Field, text: S)

Add a text field.

pub fn add_pre_tokenized_text(
    &mut self,
    field: Field,
    pre_tokenized_text: &PreTokenizedString
)

Add a pre-tokenized text field.

pub fn add_u64(&mut self, field: Field, value: u64)

Add a u64 field

pub fn add_i64(&mut self, field: Field, value: i64)

Add a i64 field

pub fn add_f64(&mut self, field: Field, value: f64)

pub fn add(&mut self, field_value: FieldValue)

Add a field value

pub fn field_values(&self) -> &[FieldValue]

field_values accessor

pub fn get_sorted_field_values(&self) -> Vec<(Field, Vec<&FieldValue>)>

The result of this method is not cached and is computed on the fly when this method is called.

pub fn get_all(&self, field: Field) -> impl Iterator<Item = &Value>

Returns all of the FieldValues associated the given field

pub fn get_first(&self, field: Field) -> Option<&Value>

Returns the first FieldValue associated the given field

pub fn prepare_for_store(&mut self)

Prepares Document for being stored in the document store

Method transforms PreTokenizedString values into String values.
