• If you are trying to use Boolean operators, they must be ALL CAPS: ho ((chieu sang) OR (chieu xanh)) - nhanh tinh quang dong cong ((san toan) OR (manh toan)) cau.
• The words AND, OR and NOT may confuse the search; try adding quotes: "ho ((chieu sang) OR (chieu xanh)) - nhanh tinh quang dong cong ((san toan) or (manh toan)) cau".
• Adding a wildcard symbol may retrieve word variants: ho ((chieu sang) OR (chieu xanh)) - nhanh tinh quang dong cong ((san toan) or (manh toan)) cau*.
