• If you are trying to use Boolean operators, they must be ALL CAPS: ho ((chieu xanh) OR (chieu sang)) - hanh chinh cua khong ((cang thanh) OR (dang thanh)) toan cau.
• The words AND, OR and NOT may confuse the search; try adding quotes: "ho ((chieu xanh) or (chieu sang)) - hanh chinh cua khong ((cang thanh) OR (dang thanh)) toan cau".
• Adding a wildcard symbol may retrieve word variants: ho ((chieu xanh) or (chieu sang)) - hanh chinh cua khong ((cang thanh) OR (dang thanh)) toan cau*.
