So you may want to give the following a try:

c:\>ppm upgrade WWW::Search
[download]

Update: Hmm, that won't help you out because it will query the activeperl repository. To re-install from Randy's repository, try the following:

c:\>ppm install http://theoryx5.uwinnipeg.ca/ppms/WWW-Search.ppd -forc
+e

I did the force option and upgraded the packages but unfortunately still an empty url1.txt file

Does the script print the results to the screen? And are you letting it run to completion? When I run it, it takes a while to complete, as there's a sleep() call in there to prevent the site from thinking you're a robot - if you abort too early, the file indeed may be empty due to buffering. Try getting, say, the first 5 results, and let it run to completion.
