• If you are trying to use Boolean operators, they must be ALL CAPS: te sach tay lang xa hoi. ((hieu ve) OR (hieu va)) cham cuu ban tinh va ((cua triet) OR (cua viet))*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "te sach tay lang xa hoi. ((hieu ve) or (hieu va)) cham cuu ban tinh va ((cua triet) OR (cua viet))*".
