<H1><A NAME="description">DESCRIPTION</A></H1>
<P>This class is a SFgate specialization of WWW::Search. It queries and
interprets searches based on SFgate, which is available at
<EM><A HREF="http://ls6-www.informatik.uni-dortmund.de/SFgate/welcome.html">http://ls6-www.informatik.uni-dortmund.de/SFgate/welcome.html</A></EM></P>
<P>This class exports no public interface; all interaction should be
done through WWW::Search objects.</P>
<P>This object rewrites URLs to use the preformatted, verbose output
format of SFgate. This allows it to get the 'score' and 'size'
information easily. The url portions it rewrites are 'verbose=1'
and 'listenv=pre'.</P>
