Yes, that would work.

It would probably be best if exceeding max_terms in the constructor  
caused an exception object to be thrown, allowing code like this:

    my $query = eval {
      KSx::Search::RegexpQuery->new(
        re => qr/^foo.*/,
        field => 'content',
        max_terms => 1024,
      );
    };
    my $exception = $@;
    if ( ref($exception) and $exception->isa('MyCustomException') ) {
       tell_user_about_error($exception);
    }
