• If you are trying to use Boolean operators, they must be ALL CAPS: ho ((((chieu sang) OR (hieu lang))) OR (chieu sach)) - anh tang van dung cong anh tuan tap~.
• Adding a wildcard symbol may retrieve word variants: ho ((((chieu sang) or (hieu lang))) or (chieu sach)) - anh tang van dung cong anh tuan tap*.
