Hi All,
I'm running some encrypted data through a script I wrote. In order to do this, I'm using eval to resolve some of my variables. At the moment, when I use eval to resolve, it strips out some of my encrypted values, and totally drops some others. For example if I have the value ab1"3 it drops... (1 Reply)

www::search::lycos
WWW::Search::Lycos(3pm) User Contributed Perl Documentation WWW::Search::Lycos(3pm)
NAME
WWW::Search::Lycos - class for searching www.lycos.com
SYNOPSIS
use WWW::Search;
my $oSearch = new WWW::Search('Lycos');
my $sQuery = WWW::Search::escape_query("+sushi restaurant +Columbus Ohio");
$oSearch->native_query($sQuery);
while (my $oResult = $oSearch->next_result())
{ print $oResult->url, "
"; }
DESCRIPTION
This class is a Lycos specialization of WWW::Search. It handles making and interpreting Lycos-site searches http://www.lycos.com.
This class exports no public interface; all interaction should be done through WWW::Search objects.
NOTES
Warning! As of 2004-01, lycos.com often returns an error page in place of the third page of results. So it is very difficult to get more
than 20 hits for any query!
www.lycos.com is sometimes slow to respond; but I have not had a problem with the default timeout.
www.lycos.com does not give the date nor size of the pages at the resulting URLs; therefore change_date() and size() will never have a
value.
SEE ALSO
To make new back-ends, see WWW::Search.
BUGS
Please tell the author if you find any!
