• If you are trying to use Boolean operators, they must be ALL CAPS: te sach v nang ((x hoi) OR (o hoi)). hieu ve cham quoc va ((danh sai) OR (danh bat)) cua tre~.
• Adding a wildcard symbol may retrieve word variants: te sach v nang ((x hoi) or (o hoi)). hieu ve cham quoc va ((danh sai) or (danh bat)) cua tre*.
