• If you are trying to use Boolean operators, they must be ALL CAPS: ho ((chieu xanh) OR (chieu tinh)) - tan tran van hung cong ((dan phan) OR (doan phan)) cac.
• The words AND, OR and NOT may confuse the search; try adding quotes: "ho ((chieu xanh) or (chieu tinh)) - tan tran van hung cong ((dan phan) OR (doan phan)) cac".
• Adding a wildcard symbol may retrieve word variants: ho ((chieu xanh) or (chieu tinh)) - tan tran van hung cong ((dan phan) OR (doan phan)) cac*.
