• If you are trying to use Boolean operators, they must be ALL CAPS: ho ((chieu xanh) OR (bi tinh)) - anh dung cho tong cong san ((toan cao) OR (toan tap)).
• The words AND, OR and NOT may confuse the search; try adding quotes: "ho ((chieu xanh) or (bi tinh)) - anh dung cho tong cong san ((toan cao) OR (toan tap))".
• Adding a wildcard symbol may retrieve word variants: ho ((chieu xanh) or (bi tinh)) - anh dung cho tong cong san ((toan cao) OR (toan tap))*.
