WWW::Search::OpenDirectory - class for searching dmoz.org!
require WWW::Search;
$search = new WWW::Search('OpenDirectory');
This class uses the Open Directory engine http://dmoz.org.
Yahoo! type directory that is user maintained. Very nice!
Seperate search terms with 'and' to include all words. Accepts
double quotes for phrase searching: ``Tour de France''
This class exports no public interface; all interaction should
be done through WWW::Search objects.
To make new back-ends, see the WWW::Search manpage,
or the specialized AltaVista searches described in options.
native_setup_search is called before we do anything.
It initializes our private variables (which all begin with underscores)
and sets up a URL to the first results page in {_next_url}.
native_retrieve_some is called (from WWW::Search::retrieve_some)
whenever more hits are needed. It calls the LWP library
to fetch the page specified by {_next_url}.
It parses this page, appending any search hits it finds to
{cache}. If it finds a ``next'' button in the text,
it sets {_next_url} to point to the page for the next
set of results, otherwise it sets it to undef to indicate we're done.
