Searching for problem-setter's tasks doesn't work.
For example I wanted to see all tasks of .:: Debanjan ::. and that's what is displayed after clicking on Debanjan's account in psetters' ranking:
http://www.spoj.pl/search/'.::%20%20Debanjan%20::.'/problems=on
Even when I paste his name into the textbox on that page it shows all sites on spoj.pl where Debanjan even posted a comment.
