NAME
WWW::Search::Yahoo - class for searching Yahoo
SYNOPSIS
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.
You can also search Yahoo Korea. Just add this search_base_url to your search setup:
$oSearch->native_query($sQuery,
{'search_base_url' => 'http://search.yahoo.co.kr'});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.
