• If you are trying to use Boolean operators, they must be ALL CAPS: su ((sach ky) OR (sach y)) ((lang xa) OR (dang xay)) hoi. hieu ve cam tuc van hang doi su triet*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "su ((sach ky) or (sach y)) ((lang xa) OR (dang xay)) hoi. hieu ve cam tuc van hang doi su triet*".
