• If you are trying to use Boolean operators, they must be ALL CAPS: (( tu danh ngon ((khong he) OR (hong ha)) đong luc ) OR ( thu sach nhap cong khi đong luc )).
• The words AND, OR and NOT may confuse the search; try adding quotes: "(( tu danh ngon ((khong he) OR (hong ha)) đong luc ) or ( thu sach nhap cong khi đong luc ))".
• Adding a wildcard symbol may retrieve word variants: (( tu danh ngon ((khong he) OR (hong ha)) đong luc ) or ( thu sach nhap cong khi đong luc ))*.
