• If you are trying to use Boolean operators, they must be ALL CAPS: doc ((hieu manh) OR (chieu xanh)) - thanh tung luan ((phuong dong) OR (chuong duong)) dan chan cau.
• The words AND, OR and NOT may confuse the search; try adding quotes: "doc ((hieu manh) OR (chieu xanh)) - thanh tung luan ((phuong dong) or (chuong duong)) dan chan cau".
• Adding a wildcard symbol may retrieve word variants: doc ((hieu manh) OR (chieu xanh)) - thanh tung luan ((phuong dong) or (chuong duong)) dan chan cau*.
