• If you are trying to use Boolean operators, they must be ALL CAPS: chao chu xanh - ((hanh bang) OR (anh bang)) va nhung cong ((dan thanh) OR (ban thanh)) cac~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "chao chu xanh - ((hanh bang) or (anh bang)) va nhung cong ((dan thanh) OR (ban thanh)) cac~".
• Adding a wildcard symbol may retrieve word variants: chao chu xanh - ((hanh bang) or (anh bang)) va nhung cong ((dan thanh) OR (ban thanh)) cac*.
