- <P>This class is an Fireball specialization of WWW::Search.
- It handles making and interpreting Fireball searches
- <EM><A HREF="http://www.fireball.de">http://www.fireball.de</A></EM>.</P>
- <P>This class exports no public interface; all interaction should
- be done through WWW::Search objects.</P>

- <P><CODE>native_setup_search</CODE> 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 <CODE>{_next_url}</CODE>.</P>
- <P><CODE>native_retrieve_some</CODE> is called (from <CODE>WWW::Search::retrieve_some</CODE>)
- whenever more hits are needed. It calls the LWP library
- to fetch the page specified by <CODE>{_next_url}</CODE>.
- It parses this page, appending any search hits it finds to
- <CODE>{cache}</CODE>. If it finds a ``next'' button in the text,
- it sets <CODE>{_next_url}</CODE> to point to the page for the next
- set of results, otherwise it sets it to undef to indicate we're done.</P>
