• If you are trying to use Boolean operators, they must be ALL CAPS: te sach lo ((hang ca) OR (nang cao)) hoi. hieu ((va cai) OR (va cham)) tuc va danh vi cua triet.
• The words AND, OR and NOT may confuse the search; try adding quotes: "te sach lo ((hang ca) OR (nang cao)) hoi. hieu ((va cai) or (va cham)) tuc va danh vi cua triet".
