• If you are trying to use Boolean operators, they must be ALL CAPS: ho chieu xanh - ((manh truong) OR (lang trong)) cua thong cong ((dan toan) OR (van toan)) tap*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "ho chieu xanh - ((manh truong) or (lang trong)) cua thong cong ((dan toan) OR (van toan)) tap*".
