HOW DOES IT WORK?
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.
