WWW::Search::WashPost(3pm)				User Contributed Perl Documentation				WWW::Search::WashPost(3pm)

NAME

       WWW::Search::WashPost - WWW::Search backend for searching www.washingtonpost.com

SYNOPSIS

	 use WWW::Search;
	 my $oSearch = new WWW::Search('WashPost');
	 my $sQuery = WWW::Search::escape_query("japan prime minister");
	 $oSearch->native_query($sQuery);
	 while (my $oResult = $oSearch->next_result())
	   { print $oResult->url, "
"; }

DESCRIPTION

       This class is a specialization of WWW::Search.  It handles making and interpreting searches on news at The Washington Post
       http://www.washingtonpost.com.

       This class exports no public interface; all interaction should be done through WWW::Search objects.

NOTES

       In the resulting WWW::SearchResult objects, the following elements will be set (in addition to the usual title, description, etc.):

       source
	   Something like "Post" or a certain "Edition".

       location
	   The page number of the print edition, e.g. "E05".

       category
	   The type of item found, either "Article" or "Photo".

       seller
	   The author or photographer.

SEE ALSO

       To make new backends, see WWW::Search.

CAVEATS

       This backend (and all its subclasses) only searches news stories from the last 14 days.	(This is a restriction on the Washington Post
       website that we can not avoid.)
