AngularJS - placeholder for empty result from filter

I want to have a place holder, e.g. <No result> when filter result returns empty. Could anyone please help? I don't even know where to start...

HTML:

<div ng-controller="Ctrl">
<h1>My Foo</h1>
<ul>
    <li ng-repeat="foo in foos">
        <a href="#" ng-click="setBarFilter(foo.name)">{{foo.name}}</a>
    </li>
</ul>
<br />
<h1>My Bar</h1>
<ul>
    <li ng-repeat="bar in bars | filter:barFilter">{{bar.name}}</li>
</ul>

</div>

JS:

function Ctrl($scope) {

  $scope.foos = [{
    name: 'Foo 1'
  },{
    name: 'Foo 2'
  },{
    name: 'Foo 3'
  }];

  $scope.bars = [{
    name: 'Bar 1',
    foo: 'Foo 1'
  },{
    name: 'Bar 2',
    foo: 'Foo 2'
  }];

  $scope.setBarFilter = function(foo_name) {
    $scope.barFilter = {};
    $scope.barFilter.foo = foo_name;
  }
}

Thanks!

A tweak on the approach that only requires you to specify the filter once:

  <li ng-repeat="bar in filteredBars = (bars | filter:barFilter)">{{bar.name}}</li>
</ul>
<p ng-hide="filteredBars.length">Nothing here!</p>

Fiddle

Here is the trick using ng-show

HTML:

<div ng-controller="Ctrl">
<h1>My Foo</h1>
<ul>
    <li ng-repeat="foo in foos">
        <a href="#" ng-click="setBarFilter(foo.name)">{{foo.name}}</a>
    </li>
</ul>
<br />
<h1>My Bar</h1>
<ul>
    <li ng-repeat="bar in bars | filter:barFilter">{{bar.name}}</li>
</ul>
<p ng-show="(bars | filter:barFilter).length == 0">Nothing here!</p>

</div>

Taken from this official document that's how they do it:

ng-repeat="friend in friends | filter:q as results"

Then use the results as an array

<li class="animate-repeat" ng-if="results.length == 0">
  <strong>No results found...</strong>
</li>

Full snippet:

<div ng-controller="repeatController">
I have {{friends.length}} friends. They are:
<input type="search" ng-model="q" placeholder="filter friends..." aria-label="filter friends" />


<ul class="example-animate-container">
    <li class="animate-repeat" ng-repeat="friend in friends | filter:q as results">
      [{{$index + 1}}] {{friend.name}} who is {{friend.age}} years old.
    </li>
    <li class="animate-repeat" ng-if="results.length == 0">
      <strong>No results found...</strong>
    </li>
  </ul>
</div>
