如何使用 angularjs 使用过滤器进行 ng-repeat？

Question

在这里我添加了我想根据用户输入搜索的代码我尝试了这个但是

filter: first_name_model

我没有得到正确的结果

例如：运行代码片段

输入“2”并查看结果（我们只需要获取一条记录，但它显示所有记录）

输入“as”并查看结果（我们只需要获取一条记录（asif yohana），但它显示了两条记录）

我只想过滤这两个字段

1.没有

2.显示名称

可能需要使用'OR'条件。

帮助我前进

angular.module('myApp', []).controller('namesCtrl', function($scope) {

    $scope.students = [{
            "firstname": "irfan",
            "lastname": "k",
			"no":"2",
            "userid": "5706b916bb729ecc876192d2"

请将输入的 ng-model 更改为 first_name_model.no 它对我有用

 <script src="https://ajax.googleapis.com/ajax/libs/angularjs/1.6.9/angular.min.js"></script>
<div ng-app="myApp" ng-controller="namesCtrl">
         filter data <input type = "text" ng-model = "first_name_model.no"/><br><br><br>
         <table>
            <tr>
               <th>Number</th>
               <th>DisplayName</th>
            </tr>

            <tr ng-repeat="student in students | filter: first_name_model">
               <td><input type="text" ng-model ="student.no"></td>

               <td>
                  <select  ng-model="student.userid"  placeholder="Assigned To" name="userid{{$index}}" >
                  <option ng-repeat="user in users | orderBy: 'DisplayName'" ng-value="user._id">
                     {{user.DisplayName}}</md-option>
                     </md-select>
               </td>
            </tr>
         </table>
      </div>
