NAME

HOW DOES IT WORK?
native_setup_search
is called (from WWW::Search::setup_search
) before we do anything. It initializes our private variables (which all begin with underscore) 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 WWW::Search::http_request
to fetch the page specified by {_next_url}
. It then 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.
