• The words AND, OR and NOT may confuse the search; try adding quotes: "su sach hoi dap, nghien cuu mon hoc nganh ((chong hoc) OR (thong hoc)) bai choi ca nhan va~".
• Adding a wildcard symbol may retrieve word variants: su sach hoi dap, nghien cuu mon hoc nganh ((chong hoc) OR (thong hoc)) bai choi ca nhan va*.
