idiomatic way to handle manager class search results?

this works, just checking to see if its the idiomatic way-- as the  
docs didn't point to it...

basically:
        a query in  a manager for non-key fields...
        results are stuffed into $results
        check scalar @$ to see if there are results

i *think* @$results is the right way to handle it.  $results is a  
rosedb object, but overloads make it seem like an arrayref

====

package MyApp::RoseDB::Object::Sample::Manager;
use Rose::DB::Object::Manager;
our @ISA = qw(Rose::DB::Object::Manager);
sub object_class { 'MyApp::RoseDB::Object:: Sample' }

sub seach_for_existence {
        my ( $class, %args ) = @_ ;
        my      $results= $class->get_item(
                        query=> [
                                linked_id=> $args{linked_id} ,
                                type_id=> $args{type_id} ,
                                resource=> $args{resource}
                        ],
                        db=> $args{db}
        );
        if ( scalar @$results ) {
                return $results;
        }
        else {
                return 0;
        }
}
