title: Angular ui-select with or conditioned filter
body: <p>I am trying to use or condition filter in ui select and I am not sure how to process that. I have a similar question answered <a href="https://stackoverflow.com/questions/27103867/angular-ui-select-filtering-only-one-field">here</a>. But that is asked for using AND condition which works for me too. Here is my code</p>
  
  <p><strong>HTML</strong></p>
  
  <pre><code>&lt;ui-select ng-model="citySelected"&gt;
      &lt;ui-select-match&gt;
          {{$select.selected.name + ', ' + $select.selected.country}}
      &lt;/ui-select-match&gt;
      &lt;ui-select-choices repeat="city in List | filter: {name: $select.search} | orderBy:'sortOrder'"&gt;
          &lt;span ng-bind-html="city.name + ', ' + city.country| highlight: $select.search"&gt;&lt;/span&gt;
      &lt;/ui-select-choices&gt;
  &lt;/ui-select&gt;
  </code></pre>
