• If you are trying to use Boolean operators, they must be ALL CAPS: theo chu xanh - ((hanh tang) OR (anh tang)) cua thuong cong san ((thanh cau) OR (thanh mau))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "theo chu xanh - ((hanh tang) OR (anh tang)) cua thuong cong san ((thanh cau) or (thanh mau))~".
• Adding a wildcard symbol may retrieve word variants: theo chu xanh - ((hanh tang) OR (anh tang)) cua thuong cong san ((thanh cau) or (thanh mau))*.
