• If you are trying to use Boolean operators, they must be ALL CAPS: te sach duc ((anh xa) OR (anh xay)) hoi. hieu va cam tuc va danh lai ((cua triet) OR (va triet))*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "te sach duc ((anh xa) or (anh xay)) hoi. hieu va cam tuc va danh lai ((cua triet) OR (va triet))*".
