NAME

WWW::Search::Fireball - class for searching Fireball

SUPPORTED PLATFORMS

This module is not included with the standard ActivePerl distribution. It is available as a separate download using PPM.

SYNOPSIS

    require WWW::Search;
    $search = new WWW::Search('Fireball');

DESCRIPTION

This class is an Fireball specialization of WWW::Search. It handles making and interpreting Fireball searches http://www.fireball.de.

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

SEE ALSO

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

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.
