• The words AND, OR and NOT may confuse the search; try adding quotes: "su sach doi dap, nghiep luat tin ((hoc toan) OR (hoc tan)) hoa hoc ma hoi van nhan dan~".
• Adding a wildcard symbol may retrieve word variants: su sach doi dap, nghiep luat tin ((hoc toan) OR (hoc tan)) hoa hoc ma hoi van nhan dan*.
