Nautilus find command not working

view story

https://bbs.archlinux.org – I have nautilus installed on archlinux and it works all right except that find file function (started by control-F) does not work properly. The find file window does open up, but, whatever I enter there, no files are picked up. I have tried 'pdf', '*pdf*', '.pdf', '*' (all without quotes) but of no avail. I have installed gnome-search-tool and that works all right. I have added this to nautilus through nautilus-actions-config-tool and there also it works all right. But I wonder why control-F find file function of nautilus does not work. Any help will be (HowTos)
