javascript - AngularJS - access elements outside of ng-view

I have a setup with an ng-view (an admin panel) that lets me display orders. I have a search box outside of ng-view that I would like to use to modify my json request. I've seen some posts on accessing things such as the title but was not able to get them to work - perhaps outdated.

Main app stuff:

angular.module('myApp', ['myApp.controllers', 'myApp.filters', 'myApp.services', 'myApp.directives', 'ui.bootstrap']).
config(['$routeProvider', '$locationProvider', function($routeProvider, $locationProvider)       {

$routeProvider.
  when('/', {
    templateUrl: '/partials/order/manage.html',
    controller: 'ManageOrderCtrl'
  }).     
  when('/order/:id', {
   templateUrl: '/partials/order/view.html',
    controller: 'ViewOrderCtrl'
  }).   
  otherwise({
    redirectTo: '/'
  });
$locationProvider.html5Mode(true);
}]);

Manage controller:

angular.module('myApp.controllers', [])
.controller('ManageOrderCtrl', ['$scope', '$http', '$dialog', 'config', 'Page', function($scope, $http, $dialog, config, Page) {

  // would like to have search value from input #search available here
  var getData = function() {
    $http.get('/orders').
    success(function(data, status, headers, config) {
      $scope.orders = data.orders;
    });
  };

getData();
})

View:

<body ng-app="myApp" >
  <input type="text" id="search">
  <div class="ng-cloak" >
    <div ng-view></div>
  </div>
</body>

If you're going to access stuff outside the <div ng-view></div>, I think a better approach would be to create a controller for the outer region as well. Then you create a service to share data between the controllers:

<body ng-app="myApp" >
  <div ng-controller="MainCtrl">
      <input type="text" id="search">
  </div>
  <div class="ng-cloak" >
    <div ng-view></div>
  </div>
</body>

(ng-controller="MainCtrl" can also be placed on the <body> tag - then the ng-view $scope would be a child of the MainCtrl $scope instead of a sibling.)

Creating the service is as simple as this:

app.factory('Search',function(){
  return {text:''};
});

And it's injectable like this:

app.controller('ManageOrderCtrl', function($scope,Search) {
  $scope.searchFromService = Search;
});

app.controller('MainCtrl',function($scope,Search){
  $scope.search = Search;
});

This way you don't have to rely on sharing data through the global $rootScope (which is kinda like relying on global variables in javascript - a bad idea for all sorts of reasons) or through a $parent scope which may or may not be present.

I've created a plnkr that tries to show the difference between the two solutions.
