• If you are trying to use Boolean operators, they must be ALL CAPS: so sach tu tang ((ma hoi) OR (((mai hoi) OR (dai hoi)))). hieu ve cham duc va hanh nam cua tre~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "so sach tu tang ((ma hoi) or (((mai hoi) OR (dai hoi)))). hieu ve cham duc va hanh nam cua tre~".
• Adding a wildcard symbol may retrieve word variants: so sach tu tang ((ma hoi) or (((mai hoi) OR (dai hoi)))). hieu ve cham duc va hanh nam cua tre*.
