[xwiki-users] Search not working in FAQ Extension

Hi Xwiki Users. I have just installed the FAQ Extension, but it's not working properly. Problem: the search function doesn't show results. I haven't a clue about it, since it doesn't show any errors. I've also tried to change FAQ.FAQSearchs' code, but it seems to be right( although I'm not a velocity expert). Xwiki Version: 6.1 Running on Windows 7 with Tomcat. Thank you.
