 *
 * The object will contain templates to be displayed, and the list of the different
 * options to be available to the user when he start a new search.
 *
 * The display of the Options is generated by the FullTextSearch app and Options
 * can be displayed in 2 places:
 *
 * - the navigation page of the app that generate the indexed content.
 *   (files, bookmarks, deck, mails, ...)
 * - the navigation page of the FullTextSearch app.
 *
 * Both pages will have different Options, and only the first one can integrate
 * a specific template.
