• If you are trying to use Boolean operators, they must be ALL CAPS: te sach y ((sang ma) OR (tang ma)) hoi. lieu va tham duoc ((va hanh) OR (va danh)) di cua triet.
• The words AND, OR and NOT may confuse the search; try adding quotes: "te sach y ((sang ma) or (tang ma)) hoi. lieu va tham duoc ((va hanh) OR (va danh)) di cua triet".
• Adding a wildcard symbol may retrieve word variants: te sach y ((sang ma) or (tang ma)) hoi. lieu va tham duoc ((va hanh) OR (va danh)) di cua triet*.
