NAME
WWW::Search::Excite - class for searching Excite
DESCRIPTION
This class is an Excite specialization of WWW::Search. It handles making and interpreting Excite searches http://www.excite.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 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.
BUGS
This module should support options and a back-end specific for news.
