• The words AND, OR and NOT may confuse the search; try adding quotes: "su cach thoi tap, nghien cuu cong ((hoc nganh) OR (hoc nhanh)) khong hoc xa hoi dap thanh van".
• Adding a wildcard symbol may retrieve word variants: su cach thoi tap, nghien cuu cong ((hoc nganh) OR (hoc nhanh)) khong hoc xa hoi dap thanh van*.
