Suggest keywords written cgi/perl

[dooballoh]

Hello.

Is there where I can find tutorial or the scripts to "suggest keywords" and "real-time 10 most searched keywords" written in cgi/perl?

Example like;
THIS SITE (http://naver.com) and try to type "test" in search box.

AND THIS (http://search.naver.com/search.naver?where=nexearch&query=test&frm=t1&sm=top_hty&x=32&y=11) if you look at right, real-time most searched words are displaying with arrows ups and downs.

I think that is a combination with AJAX and cgi (or php, but I want to learn in cgi.)

Thank you in advance.

most likely uses a file or database to populate the menus then javascript to jump to keywords as they are typed in. View the source code of the page and you can probably determine how it's done.
