• If you are trying to use Boolean operators, they must be ALL CAPS: (ngan OR nhan) hang khoa luan ket chua trieu thi minh doanh ((hoa tin) OR (hoat tinh))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "(ngan or nhan) hang khoa luan ket chua trieu thi minh doanh ((hoa tin) OR (hoat tinh))~".
• Adding a wildcard symbol may retrieve word variants: (ngan or nhan) hang khoa luan ket chua trieu thi minh doanh ((hoa tin) OR (hoat tinh))*.
