• If you are trying to use Boolean operators, they must be ALL CAPS: ((theo chu) OR (ho chieu)) xanh - anh bang luan ((nhung cong) OR (hang cong)) dan chan cau.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((theo chu) or (ho chieu)) xanh - anh bang luan ((nhung cong) OR (hang cong)) dan chan cau".
• Adding a wildcard symbol may retrieve word variants: ((theo chu) or (ho chieu)) xanh - anh bang luan ((nhung cong) OR (hang cong)) dan chan cau*.
