• If you are trying to use Boolean operators, they must be ALL CAPS: tu ((sach ly) OR (sach lo)) nang ma hoa. hieu ve cham tuc ((va dinh) OR (van dinh)) vi cua te*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu ((sach ly) or (sach lo)) nang ma hoa. hieu ve cham tuc ((va dinh) OR (van dinh)) vi cua te*".
