• If you are trying to use Boolean operators, they must be ALL CAPS: nuoc ((sach thu) OR (sach tham)) xang ma hoi. hieu ve cac duc va dinh viet ((cua tre) OR (cua te))*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "nuoc ((sach thu) OR (sach tham)) xang ma hoi. hieu ve cac duc va dinh viet ((cua tre) or (cua te))*".
