NAME

WWW::Search::Yahoo - class for searching Yahoo

DESCRIPTION

This class is an Yahoo specialization of WWW::Search. It handles making and interpreting Yahoo searches http://www.yahoo.com.

This class exports no public interface; all interaction should be done through WWW::Search objects.

SEE ALSO

To make new back-ends, see WWW::Search.

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.
