• If you are trying to use Boolean operators, they must be ALL CAPS: te sach ky ((lang xa) OR (((lang van) OR (hoang van)))) hoi. hieu van hoc toc va doanh dan cua te~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "te sach ky ((lang xa) or (((lang van) OR (hoang van)))) hoi. hieu van hoc toc va doanh dan cua te~".
• Adding a wildcard symbol may retrieve word variants: te sach ky ((lang xa) or (((lang van) OR (hoang van)))) hoi. hieu van hoc toc va doanh dan cua te*.
