If you ever need to show a container only if the filters of the repeated elements have one or more results, then you can do it using this code.
<input ng-model='searchText'/>
<span ng-show='filtered.length > 0'> <ul>
<li ng-repeat='el in filtered = (model | filter:searchText)'>
<div>{{el.label}}</div>
</li>
</ul>
</span>
