• If you are trying to use Boolean operators, they must be ALL CAPS: te sach y dang xay hoi. hieu van cam cuc ban hanh vai ((cua tre) OR (((cua triet) OR (cua viet))))*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "te sach y dang xay hoi. hieu van cam cuc ban hanh vai ((cua tre) or (((cua triet) OR (cua viet))))*".
