• If you are trying to use Boolean operators, they must be ALL CAPS: ho ((chieu xanh) OR (chinh sach)) - hanh trinh cua khong ((truong tinh) OR (truong dinh)) toan tap*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "ho ((chieu xanh) or (chinh sach)) - hanh trinh cua khong ((truong tinh) OR (truong dinh)) toan tap*".
