title: AngularJS Filter property from the first item on an array
body: <p>I have an array of items which contains an array of other items. The user can filter these items filling a form in the interface. It's working, but now I have a filter that need to execute just for the first item of an array that is inside of these items. What "I want" to do is this:</p>
  
  <pre><code>&lt;tr ng-repeat="item in items | filter: itemSearch | filter: {
                      my_object: { 
                          propertyA: items_filter.propertyA,
                          propertyB: items_filter.propertyB,
                          propertyC[0].status: items_filter.status //here
                      }
                  }"&gt;&lt;/tr&gt;
  </code></pre>
  
  <p>I'm getting the error:</p>
  
  <pre><code>vendor.min.js:16631 Error: [$parse:syntax] Syntax Error: Token '[' is unexpected, expecting [}] at column 401 of the expression [items | filter: itemsSearch | filter: {
  </code></pre>
  
  <p>How can I filter a property of the array's first item?</p>
