• The words AND, OR and NOT may confuse the search; try adding quotes: "te cach ((thoi dap) OR (hoi dap)), nghien cuu hoan hoc doanh khoa hoc xa hoi ca nhan van~".
• Adding a wildcard symbol may retrieve word variants: te cach ((thoi dap) OR (hoi dap)), nghien cuu hoan hoc doanh khoa hoc xa hoi ca nhan van*.
