• If you are trying to use Boolean operators, they must be ALL CAPS: ho ((nhieu tang) OR (hieu lang)) - hanh tranh va nang ((song dan) OR (cong dan)) toan tap~.
• Adding a wildcard symbol may retrieve word variants: ho ((nhieu tang) or (hieu lang)) - hanh tranh va nang ((song dan) or (cong dan)) toan tap*.
