• If you are trying to use Boolean operators, they must be ALL CAPS: ho ((chieu sang) OR (chieu xanh)) - thanh thang va ((thuong cong) OR (thuong con)) van toan ban.
• The words AND, OR and NOT may confuse the search; try adding quotes: "ho ((chieu sang) or (chieu xanh)) - thanh thang va ((thuong cong) OR (thuong con)) van toan ban".
