• If you are trying to use Boolean operators, they must be ALL CAPS: toc sach y sang ma hoi. thien van cam duc va ((tinh va) OR (((dinh lam) OR (dinh van)))) cua tre*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "toc sach y sang ma hoi. thien van cam duc va ((tinh va) or (((dinh lam) OR (dinh van)))) cua tre*".
