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