• If you are trying to use Boolean operators, they must be ALL CAPS: ((hoi hieu) OR (moi hieu)) lang - nhanh lang ((vua nhung) OR (va nhung)) cong thanh toan ban~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((hoi hieu) or (moi hieu)) lang - nhanh lang ((vua nhung) OR (va nhung)) cong thanh toan ban~".
• Adding a wildcard symbol may retrieve word variants: ((hoi hieu) or (moi hieu)) lang - nhanh lang ((vua nhung) OR (va nhung)) cong thanh toan ban*.
