• If you are trying to use Boolean operators, they must be ALL CAPS: ((su sach) OR (nuoc sach)) ky trang xa hoi. hieu ve cham ((tuc va) OR (thuc va)) danh vi cua triet.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((su sach) or (nuoc sach)) ky trang xa hoi. hieu ve cham ((tuc va) OR (thuc va)) danh vi cua triet".
