If you want to run some custom filter logic you can create a function which takes the array element as an argument and returns true or false based on whether it should be in the search results. Then pass it to the filter instruction just like you do with the search object, for example:
JS:
$scope.filterFn = function(car)
{
// Do some tests
if(car.carDetails.doors > 2)
{
return true; // this will be listed in the results
}
return false; // otherwise it won't be within the results
};
HTML:
...
<article data-ng-repeat="result in results | filter:search | filter:filterFn" class="result">
...
As you can see you can chain many filters together, so adding your custom filter function doesn’t force you to remove the previous filter using the search object (they will work together seamlessly).
