• If you are trying to use Boolean operators, they must be ALL CAPS: ho ((hieu lang) OR (hieu manh)) - hanh tinh cua ((nhung van) OR (thong cong)) van thanh van~.
• Adding a wildcard symbol may retrieve word variants: ho ((hieu lang) or (hieu manh)) - hanh tinh cua ((nhung van) or (thong cong)) van thanh van*.
