WWW::Search::SFgate - class for searching SFgate/Wais search engine
require WWW::Search; $search = new WWW::Search('SFgate');
This class is a SFgate specialization of WWW::Search. It queries and interprets searches based on SFgate, which is available at http://ls6-www.informatik.uni-dortmund.de/SFgate/welcome.html
This class exports no public interface; all interaction should be done through WWW::Search objects.
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'.
This search supports standard WWW::Search arguments
