   * Allows the caller to register for various events fired by the host search experience.
   * Calling this function indicates that your application intends to plug into the host's search box and handle search events,
   * when the user is actively using your page/tab.
   *
   * The host may visually update its search box, e.g. with the name or icon of your application.
   *
   * Your application should *not* re-render inside of these callbacks, there may be a large number
   * of onChangeHandler calls if the user is typing rapidly in the search box.
   *
   * @param onClosedHandler - This handler will be called when the user exits or cancels their search.
   * Should be used to return your application to its most recent, non-search state. The value of {@link SearchQuery.searchTerm}
   * will be whatever the last query was before ending search.
   *
   * @param onExecuteHandler - The handler will be called when the user executes their
   * search (by pressing Enter for example). Should be used to display the full list of search results.
   * The value of {@link SearchQuery.searchTerm} is the complete query the user entered in the search box.
   *
   * @param onChangeHandler - This optional handler will be called when the user first starts using the
   * host's search box and as the user types their query. Can be used to put your application into a
   * word-wheeling state or to display suggestions as the user is typing.
   *
   * This handler will be called with an empty {@link SearchQuery.searchTerm} when search is beginning, and subsequently,
   * with the current contents of the search box.
   * @example
   * ``` ts
   * search.registerHandlers(
      query => {
        console.log('Update your application to handle the search experience being closed. Last query: ${query.searchTerm}');
      },
      query => {
