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