/**
 * @name Index App Content
 * @description
 * This plugin gives you a Javascript API to interact with Core Spotlight on iOS (=> iOS 9).
 * You can add, update and delete items to the spotlight search index.
 * Spotlight Search will include these items in the result list. You can deep-link the search results with your app.
 *
 * @usage
 * ```typescript
 * import { IndexAppContent } from '@ionic-native/index-app-content/ngx';
 *
 *
 * constructor(private indexAppContent: IndexAppContent) { }
 *
 * ...
 *
 * var items = [
 *      {
 *        domain: 'com.my.domain',
 *        identifier: '88asdf7dsf',
 *        title: 'Foo',
 *        description: 'Bar',
 *        url: 'http://location/of/my/image.jpg',
 *    },
 *    {
 *        domain: 'com.other.domain',
 *        identifier: '9asd67g6a',
 *        title: 'Baz',
 *        description: 'Woot',
 *        url: 'http://location/of/my/image2.jpg',
