• The words AND, OR and NOT may confuse the search; try adding quotes: "ho chieu xanh - hanh dong ((luan thong) OR (luan tuong)) thong tan ((nhan tai) or (toan ban))~".
• Adding a wildcard symbol may retrieve word variants: ho chieu xanh - hanh dong ((luan thong) OR (luan tuong)) thong tan ((nhan tai) or (toan ban))*.
