• If you are trying to use Boolean operators, they must be ALL CAPS: thu sach y nang ((me hoi) OR (ma hoa)). hieu va ((cac tac) OR (cac toc)) xa danh ca cua tre.
• The words AND, OR and NOT may confuse the search; try adding quotes: "thu sach y nang ((me hoi) or (ma hoa)). hieu va ((cac tac) OR (cac toc)) xa danh ca cua tre".
• Adding a wildcard symbol may retrieve word variants: thu sach y nang ((me hoi) or (ma hoa)). hieu va ((cac tac) OR (cac toc)) xa danh ca cua tre*.
