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