• If you are trying to use Boolean operators, they must be ALL CAPS: ((doc hieu) OR (theo chieu)) xanh - lanh manh va nang ((cuong anh) OR (duong anh)) toan cao.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((doc hieu) or (theo chieu)) xanh - lanh manh va nang ((cuong anh) OR (duong anh)) toan cao".
• Adding a wildcard symbol may retrieve word variants: ((doc hieu) or (theo chieu)) xanh - lanh manh va nang ((cuong anh) OR (duong anh)) toan cao*.
