## SYNOPSIS
      use [WWW::Search](https://www.chedong.com/phpMan.php/perldoc/WWW%3A%3ASearch/markdown);
      my $oSearch = new [WWW::Search](https://www.chedong.com/phpMan.php/perldoc/WWW%3A%3ASearch/markdown)('[Null::Empty](https://www.chedong.com/phpMan.php/perldoc/Null%3A%3AEmpty/markdown)');
      $oSearch->native_query('Makes no difference what you search for...');
      my @aoResults = $oSearch->results;
      # You get no results...
      my $oResponse = $oSearch->response;
      # ...But you get an [HTTP::Response](https://www.chedong.com/phpMan.php/perldoc/HTTP%3A%3AResponse/markdown) object with a code of 200

## DESCRIPTION
    This class is a specialization of [WWW::Search](https://www.chedong.com/phpMan.php/perldoc/WWW%3A%3ASearch/markdown) that returns no hits, but no error message.

    This module might be useful for testing a client program without actually being connected to any
    particular search engine.
