• If you are trying to use Boolean operators, they must be ALL CAPS: ho nhieu tang - ((anh bang) OR (canh tranh)) cua thong ((cong ban) OR (cong san)) hang cau~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "ho nhieu tang - ((anh bang) or (canh tranh)) cua thong ((cong ban) OR (cong san)) hang cau~".
• Adding a wildcard symbol may retrieve word variants: ho nhieu tang - ((anh bang) or (canh tranh)) cua thong ((cong ban) OR (cong san)) hang cau*.
