SYNOPSIS
use WWW::Search;
my $oSearch = new WWW::Search('Infoseek');
my $sQuery = WWW::Search::escape_query("+sushi restaurant +Columbus Ohio");

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.
