WWW::Search::Profusion - class for searching Profusion.com!
require WWW::Search; $search = new WWW::Search('Profusion');
This class uses the Meta Search Engine http://www.profusion.com. Search engines searched are: 1) AltaVista 2) InfoSeek 3) Snap 4) Excite 5) LookSmart 6) WebCrawler 7) Magellan 8) Yahoo 9) GoTo
Most of the above defaults to Boolean. Profusion returns all retrieved hits to one page, so, there is no next page retrievals.
This class exports no public interface; all interaction should be done through WWW::Search objects.
There is 5 possible option values for type of search (default is All): Simple All Any Boolean Phrase
To search different categories with Profusion you simpy change the the base search_url to one of the following:
Newsgroups = http://usenet.profusion.com/ Health = http://health.profusion.com/ Entertainment = http://entertainment.profusion.com/ Sports = http://sports.profusion.com/ MP3 = http://mp3.profusion.com/
You can turn on totalverify=0 to weed out any bad links returned, but be warned it is slowwwwww. totalverify=20 would verify first 20 links and so on....
To make new back-ends, see WWW::Search, or the specialized AltaVista searches described in options.
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_setup_search
{_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.
