Implementations

impl Index

pub fn new<I>(fields: I) -> Selfwhere
    I: IntoIterator,
    I::Item: AsRef<str>,

Create a new index with the provided fields.

Example

let mut index = Index::new(&["title", "body", "breadcrumbs"]);
index.add_doc("1", &["How to Foo", "First, you need to `bar`.", "Chapter 1 > How to Foo"]);

Panics

Panics if multiple given fields are identical.

pub fn with_language<I>(lang: Language, fields: I) -> Selfwhere
    I: IntoIterator,
    I::Item: AsRef<str>,

Create a new index with the provided fields for the given Language.

Example

let mut index = Index::with_language(Language::English, &["title", "body"]);
index.add_doc("1", &["this is a title", "this is body text"]);

Panics

Panics if multiple given fields are identical.

pub fn add_doc<I>(&mut self, doc_ref: &str, data: I)where
    I: IntoIterator,
    I::Item: AsRef<str>,

Add the data from a document to the index.

NOTE: The elements of data should be provided in the same order as the fields used to create the index.

Example

let mut index = Index::new(&["title", "body"]);
index.add_doc("1", &["this is a title", "this is body text"]);
