AngularJS - limitTo & filter

Question

I am trying to use angular's limitTo and filter in conjunction but it does not seem to be working properly. I want to be able to enter a value into the search box, then press search. Afterwards, I want to limit the results displayed by entering a number in the filter box and press apply filter. However, when I enter a number there, instead of restricting the results to that amount, it instead clears all results. Any suggestions? For example, try searching simon. Then, enter 2 in the top box and click apply filter and see what happens.

angular.module('userApp', []).controller('myCtrl', function($scope) {

  var vm = this;

   $scope.users = [
    {'username':'david', 'email':'something@gmail.com', 'name':'Some Name'},
    {'username':'michael', 'email':'something@gmail.com', 'name':'Some Name'},
    {'username':'ben', 'email':'something@gmail.com', 'name':'Some Name'},
    {'username':'simon', 'email':'something@gmail.com', 'name':'Some Name'},
    {'username':'allen', 'email':'something@gmail.com', 'name':'Some Name'},
    {'username':'crystal', 'email':'something@gmail.com', 'name':'Some Name'},
    {'username':'meth', 'email':'something@gmail.com', 'name':'Some Name'},
    {'username':'bryan', 'email':'something@gmail.com', 'name':'Some Name'},
    {'username':'simon', 'email':'something@gmail.com', 'name':'Some Name'},
    {'username':'simon', 'email':'something@gmail.com', 'name':'Some Name'}
    ];

    vm.showAll = function() {
      $scope.limit = undefined;
    };

    vm.showMore = function(display) {
      $scope.limit = display;
    };

    vm.search = function(searchBar) {
      $scope.searchKeyword = searchBar;
    };

});

You should turn them around, as is it limits first, and then it does the filtering. So change your html to:

<tr ng-repeat="person in users | filter: searchKeyword | limitTo: limit">
