You can use the current value of query to decide when you want to fire the call:

$scope.$watch("query", function (value) {

    //implement rule here for value
    //example value is at least 3 characters
    if (value && value.length > 3) {

        $scope.loading = true;
        returnFactory.query($scope.query).then(function (returns) {
            $scope.returns = returns;
            $scope.loading = false;
        });
    }
});
