• If you are trying to use Boolean operators, they must be ALL CAPS: ho ((chieu sang) OR (hieu manh)) - anh bang luan nhung cong ((dan toan) OR (thanh san)) cau~.
• Adding a wildcard symbol may retrieve word variants: ho ((chieu sang) or (hieu manh)) - anh bang luan nhung cong ((dan toan) or (thanh san)) cau*.
