• If you are trying to use Boolean operators, they must be ALL CAPS: te sach xu nang ((ma hoa) OR (mai hoi)). hieu ((ve cam) OR (va cam)) duc va lang hai cua te*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "te sach xu nang ((ma hoa) or (mai hoi)). hieu ((ve cam) OR (va cam)) duc va lang hai cua te*".
