• If you are trying to use Boolean operators, they must be ALL CAPS: te cao ky sang mai hoi. hieu ve ((giao duc) OR (cam xuc)) va ((danh lai) OR (danh sai)) cuoc tre.
• The words AND, OR and NOT may confuse the search; try adding quotes: "te cao ky sang mai hoi. hieu ve ((giao duc) or (cam xuc)) va ((danh lai) OR (danh sai)) cuoc tre".
