• The words AND, OR and NOT may confuse the search; try adding quotes: "ho ((nhieu tang) OR (hieu lang)) - hanh truong cao hang cong tan ((tra cau) or (tran chau))~".
• Adding a wildcard symbol may retrieve word variants: ho ((nhieu tang) OR (hieu lang)) - hanh truong cao hang cong tan ((tra cau) or (tran chau))*.
