I figured it out- I had to write my own custom filter. Here is my solution:

var filteredData;

filteredData = $filter('filter')(data, function(data) {
  if ($scope.filter) {
    return data.id.toString().indexOf($scope.filter) > -1 || data.name.toString().indexOf($scope.filter) > -1;
  } else {
    return true;
  }
});

Easily We can do this type Following written code according you will easily create another field filter....

var myApp = angular.module('myApp',[]);

myApp.filter('myfilter',myfilter);

function myfilter(){
   return function (items, filters) {
        
        if (filters == null) {
            return items;
        }

        var filtered = [];
        //Apply filter
        angular.forEach(items, function (item) { 
            if ((filters.Name == '' || angular.lowercase(item.Name).indexOf(angular.lowercase(filters.Name)) >= 0) 
               )
            {
                filtered.push(item);
            }

        });
        return filtered;
    };
}

myApp.controller('mycontroller',['$scope',function($scope){
  $scope.filters={Name:'',MathsMarks:''};
  $scope.students=[];
  var i=0;
  for(i=0;i<5;i++){
    var item={Name:'',Marks:[]};
  
    item.Name='student' + i;  
    item.Marks.push({Maths:50-i,Science:50 +i});
    
    $scope.students.push(item);
  }

}]);

<html ng-app='myApp'>
  <head>
<script src="https://ajax.googleapis.com/ajax/libs/angularjs/1.2.21/angular.min.js"></script>
</head>
  <body ng-controller='mycontroller'>
    <input type='text' name='studentName' ng-model="filters.Name" placeholder='Enter Student Name'>
    <div ng-repeat="student in students | myfilter: filters">
      Name : {{student.Name}} Marks == >
      <span ng-repeat="m in student.Marks">Maths:{{m.Maths}} Science:{{m.Science}}</span>
      </div>
  </body>
</html>
