• If you are trying to use Boolean operators, they must be ALL CAPS: vu sach ((ty nang) OR (ty hang)) ((ma hoi) OR (ma hoa)). hieu ve cac nuoc va hanh di cua tre~.
• Adding a wildcard symbol may retrieve word variants: vu sach ((ty nang) or (ty hang)) ((ma hoi) or (ma hoa)). hieu ve cac nuoc va hanh di cua tre*.
