• The words AND, OR and NOT may confuse the search; try adding quotes: "hoc ((chieu xanh) or (((chieu sach) OR (chieu sang)))) - hanh trung thanh tung phuong dan van ban~".
• Adding a wildcard symbol may retrieve word variants: hoc ((chieu xanh) or (((chieu sach) OR (chieu sang)))) - hanh trung thanh tung phuong dan van ban*.
