• If you are trying to use Boolean operators, they must be ALL CAPS: doi chi hanh - hanh ((luong quan) OR (tong quan)) duong ((cong danh) OR (cuong danh)) toan cao*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "doi chi hanh - hanh ((luong quan) or (tong quan)) duong ((cong danh) OR (cuong danh)) toan cao*".
