• The words AND, OR and NOT may confuse the search; try adding quotes: "((hoc hien) OR (doi chi)) xanh - hanh tranh cua nhung huong ((dan than) OR (ban than)) cau~".
• Adding a wildcard symbol may retrieve word variants: ((hoc hien) OR (doi chi)) xanh - hanh tranh cua nhung huong ((dan than) OR (ban than)) cau*.
