• If you are trying to use Boolean operators, they must be ALL CAPS: doc ((hieu nganh) OR (vien nganh)) - thanh tuong ((cua thuong) OR (ca thuong)) cong san than cau*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "doc ((hieu nganh) OR (vien nganh)) - thanh tuong ((cua thuong) or (ca thuong)) cong san than cau*".
