filter multiple fields using single input in AngularJS

Question

I have a JSON object which is as follows

[{
    "id": 1,
    "firstName": "Jennifer",
    "middleName": null,
    "lastName": "Aniston",
    "address": "New York City",
}, {
    "id": 2,
    "firstName": "Angelina",
    "middleName": null,
    "lastName": "Jolie",
    "address": "Beverley Hills",
}, {
    "id": 3,
    "firstName": "Emma",
    "middleName": null,
    "lastName": "Watson",
    "address": "London",
}]

I'm populating this data in view using ng-repeat.

<td ng-repeat="row in list | filter:filterBeauties">
{{row.firstName}} {{row.lastName}}
</td>

Now I have an input box which I'd like to use to filter these names. I would like to use same input box to filter firstName and then filter lastName and don't filter anything else (eg. address).

<input type="text" placeholder="Filter" ng-model="filterBeauties.firstName">

Any idea how can I achieve it?

Try this fiddle.

Essentially, I created a sub-structure for filtering within the data structure being displayed and filter only on that property (e.g. 'filterTerms'):

HTML:

<div ng-controller="MyCtrl">
   <input type="text" ng-model="search.filterTerms">
   <table border="1">
      <tr ng-repeat="row in list | filter:search">
         <td>{{row.firstName}} {{row.lastName}}</td>
      </tr>
   </table>
</div>

JavaScript:

var myApp = angular.module('myApp',[]);
function MyCtrl($scope) {
$scope.list = [{
    "id": 1,
    "address": "New York City",
    "firstName": "Jennifer",
    "middleName": null,
    "lastName": "Aniston",
    "filterTerms": {
        "firstName": "Jennifer",
        "middleName": null,
        "lastName": "Aniston",
    }
}, {
    "id": 1,
    "address": "New York City",
    "firstName": "Jennifer",
    "middleName": null,
    "lastName": "Leela",
    "filterTerms": {
        "firstName": "Jennifer",
        "middleName": null,
        "lastName": "Leela",            
    }
}, {
    "id": 2,
    "address": "Beverley Hills",
    "firstName": "Angelina",
    "middleName": null,
    "lastName": "Jolie",
    "filterTerms": {
        "firstName": "Angelina",
        "middleName": null,
        "lastName": "Jolie",            
    }
}, {
    "id": 3,
    "address": "London",
    "firstName": "Emma",
    "middleName": null,
    "lastName": "Watson",
    "filterTerms": {
        "firstName": "Emma",
        "middleName": null,
        "lastName": "Watson",            
    }
}];
}

You could simplify this even further for this case by putting all the names into one field (see fiddle here:

HTML:

<div ng-controller="MyCtrl">
    <input type="text" ng-model="search.filterTerm" />
    <table border="1">
        <tr ng-repeat="row in list | filter:search">
            <td>{{row.first}} {{row.last}} {{row.address}}</td>
        </tr>
    </table>
</div>

JavaScript:

var myApp = angular.module('myApp', []);
function MyCtrl($scope) {
    $scope.list = [{
        "id": 0, "first": "Jenny", "last": "Sorenson", "address": "123 W. Wallnut St.",
        "filterTerm": "Jenny Sorenson"
    },{
        "id": 0, "first": "Susan", "last": "Hinkle", "address": "456 W. Doorbell Dr.",
        "filterTerm": "Susan Hinkle"
    },{
        "id": 0, "first": "Rachel", "last": "Karlyle", "address": "789 W. Sunset Blvd.",
        "filterTerm": "Rachel Karlyle"
    },{
        "id": 0, "first": "Gwen", "last": "Lippi", "address": "0 W. Silly Cir.",
        "filterTerm": "Gwen Lippi"
    }]
}
