Overview

At a high level you configure Js Search by telling it which fields it should index for searching and then add the objects to be searched.

import { Search } from '@immutabl3/lunr';

var theGreatGatsby = {
  isbn: '9781597226769',
  title: 'The Great Gatsby',
  author: {
    name: 'F. Scott Fitzgerald'
  },
  tags: ['book', 'inspirational']
};
var theDaVinciCode = {
  isbn: '0307474275',
  title: 'The DaVinci Code',
  author: {
    name: 'Dan Brown'
  },
  tags: ['book', 'mystery']
};
var angelsAndDemons = {
  isbn: '074349346X',
  title: 'Angels & Demons',
  author: {
    name: 'Dan Brown',
  },
  tags: ['book', 'mystery']
};

var search = Search('isbn');
search.addIndex('title');
search.addIndex(['author', 'name']);
search.addIndex('tags')

search.addDocuments([theGreatGatsby, theDaVinciCode, angelsAndDemons]);

search.search('The');    // [theGreatGatsby, theDaVinciCode]
search.search('scott');  // [theGreatGatsby]
search.search('dan');    // [angelsAndDemons, theDaVinciCode]
search.search('mystery') // [angelsAndDemons, theDaVinciCode]
