• The words AND, OR and NOT may confuse the search; try adding quotes: "tu sach hoi dap, nghiep cay cong hoc nganh ((khoa hoc) OR (hoa hoc)) ma hoi danh nhan van~".
• Adding a wildcard symbol may retrieve word variants: tu sach hoi dap, nghiep cay cong hoc nganh ((khoa hoc) OR (hoa hoc)) ma hoi danh nhan van*.
