• The words AND, OR and NOT may confuse the search; try adding quotes: "te sach ((doi dap) OR (hoi dap)), nghien cuu mo hoc nhanh chong hoc mai hoi va nhan dan~".
• Adding a wildcard symbol may retrieve word variants: te sach ((doi dap) OR (hoi dap)), nghien cuu mo hoc nhanh chong hoc mai hoi va nhan dan*.
