• If you are trying to use Boolean operators, they must be ALL CAPS: ((te sach) OR (thu sach)) ky sang ma hoi. lieu va cam tuc van tuan ((di hoa) OR (doi hoa)) viet~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((te sach) or (thu sach)) ky sang ma hoi. lieu va cam tuc van tuan ((di hoa) OR (doi hoa)) viet~".
• Adding a wildcard symbol may retrieve word variants: ((te sach) or (thu sach)) ky sang ma hoi. lieu va cam tuc van tuan ((di hoa) OR (doi hoa)) viet*.
