• If you are trying to use Boolean operators, they must be ALL CAPS: te sach ky ((dang mau) OR (dang nam)) hoi. hieu ve cam tuc va ((thanh va) OR (hanh va)) cua triet.
• The words AND, OR and NOT may confuse the search; try adding quotes: "te sach ky ((dang mau) or (dang nam)) hoi. hieu ve cam tuc va ((thanh va) OR (hanh va)) cua triet".
