Angularjs - Filter one column with multiple option select input

Im trying to filter a single column using a select with multiple options. As soon as I select more than 2 options, the filter breaks and return me 0 results when I am expecting to return the options I selected.

Example if I select Apple and Grape, I should see all items that match my options.

Here an example of my data:

$scope.products = [
    {name:"Apple",type:"fruit"},
    {name:"Grape",type:"fruit"},
    {name:"Orage",type:"fruit"},
    {name:"Carrot",type:"vegetable"},
    {name:"Milk",type:"dairy"}
]

Here is my HTML

<div ng-controller="MyCtrl">
    <select multiple ng-model="Search_by_name">
     <option value="Apple">Apple</option>
      <option value="Grape">Grape</option>
       <option value="Orage">Orage</option>
        <option value="Carrot">Carrot</option>
         <option value="Milk">Milk</option>
    </select>
    <ul>
        <li ng-repeat="item in products | filter:{name: Search_by_name }">{{item.name}}</li>
    </ul>
</div>

You can create a custom filter function in controller :

$scope.multipleFilter = function(filterCriteria) {
  return function(item) {
    return (!filterCriteria || filterCriteria.indexOf(item.name) > -1 );
  }
};

In the html you can use it like that

<li ng-repeat="item in products | filter: multipleFilter(Search_by_name)">{{item.name}}</li>
