• If you are trying to use Boolean operators, they must be ALL CAPS: ((su sach) OR (vu sach)) y mang tay hoi. lieu va tham loc va danh vi ((cua triet) OR (cua viet))*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((su sach) OR (vu sach)) y mang tay hoi. lieu va tham loc va danh vi ((cua triet) or (cua viet))*".
