• If you are trying to use Boolean operators, they must be ALL CAPS: ((te sach) OR (thuoc sach)) tay lang ha hoi. ((hieu ve) OR (hieu va)) cham tu van anh vi cua te~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((te sach) or (thuoc sach)) tay lang ha hoi. ((hieu ve) OR (hieu va)) cham tu van anh vi cua te~".
• Adding a wildcard symbol may retrieve word variants: ((te sach) or (thuoc sach)) tay lang ha hoi. ((hieu ve) OR (hieu va)) cham tu van anh vi cua te*.
