NAME
WWW::Search::Yahoo::News::Advanced - class for searching Yahoo! News
using the "advanced" interface
SYNOPSIS
use WWW::Search;
my $oSearch = new WWW::Search('Yahoo::News::Advanced');
my $sQuery = WWW::Search::escape_query("George Lucas");
$oSearch->date_from('2001-05-05');
$oSearch->date_to( '2001-07-05');
$oSearch->native_query($sQuery);
while (my $oResult = $oSearch->next_result())
print $oResult->url, "\n";DESCRIPTION
This class is a Yahoo! News specialization of WWW::Search. It
handles making and interpreting searches on Yahoo! News
http://search.news.yahoo.com using the Advanced search interface.
This class exports no public interface; all interaction should
be done through WWW::Search objects.
NOTES
This backend supports narrowing the search by date-range.
Use date_from() and date_to() to set the endpoints of the desired date range.
You can use any date format supported by the Date::Manip module.
If either date endpoint is not set explicitly,
it will search with an appropriately open-ended date range.
NOTE that Yahoo only keeps the last 90 days worth of news in its index.
ALSO NOTE that Yahoo will return an ERROR if date_from() is set to
anything prior to Jan. 1 1999. This backend does NOT check for that.
News.yahoo.com dies if the unescaped query is longer than 485
characters or so. This backend does NOT check for that.

To make new back-ends, see WWW::Search.
