fuse.js

Simple Search

This feature allows you to perform a simple fuzzy search on a list of items. The code sample demonstrates searching for the term 'old man' in an array of book titles.

const Fuse = require('fuse.js');
const books = [{ title: 'Old Man's War' }, { title: 'The Lock Artist' }];
const fuse = new Fuse(books, { keys: ['title'] });
const result = fuse.search('old man');

Weighted Search

This feature allows you to perform a search where each field can have a different weight, affecting the relevance of search results. The code sample demonstrates a weighted search where the author field has a higher weight than the title.

const Fuse = require('fuse.js');
const books = [{ title: 'Old Man's War', author: 'John Scalzi' }, { title: 'The Lock Artist', author: 'Steve Hamilton' }];
const fuse = new Fuse(books, { keys: [{ name: 'title', weight: 0.3 }, { name: 'author', weight: 0.7 }] });
const result = fuse.search('john');

Extended Search

This feature allows you to use an extended search syntax to perform searches that include logical operators. The code sample demonstrates searching for items that do not include the word 'lock'.

const Fuse = require('fuse.js');
const books = [{ title: 'Old Man's War' }, { title: 'The Lock Artist' }];
const options = { includeMatches: true, useExtendedSearch: true };
const fuse = new Fuse(books, options);
const result = fuse.search('!lock');
