• If you are trying to use Boolean operators, they must be ALL CAPS: ((thuat lanh) OR (su sach)) ky lang hai hai. hieu ((ve cam) OR (va cam)) luc va dinh vai cua tre~.
• Adding a wildcard symbol may retrieve word variants: ((thuat lanh) or (su sach)) ky lang hai hai. hieu ((ve cam) or (va cam)) luc va dinh vai cua tre*.
