NAME
WWW::Search::Yahoo - class for searching YahooSYNOPSIS
use WWW::Search; my $oSearch = new WWW::Search('Yahoo'); my $sQuery = WWW::Search::escape_query("sushi restaurant Columbus Ohio"); $oSearch->native_query($sQuery); while (my $oResult = $oSearch->next_result()) print $oResult->url, "\n";
DESCRIPTION
This class is a Yahoo specialization of WWW::Search. It handles making and interpreting Yahoo searches http://www.yahoo.com.This class exports no public interface; all interaction should be done through WWW::Search objects.
NOTES
The default search is: Yahoo's Inktomi-based index (not usenet).The default search is the ``OR'' of all query terms (not ``AND''). If you want the ``AND'' of all the query terms, add {'za' => 'and'} to the second argument to native_query. If you want to search the query as a phrase, add {'za' => 'phrase'} to the second argument to native_query. If you want to search the query as Yahoo's ``intelligent default'' (whatever that means), add {'za' => 'default'} to the second argument to native_query.
