• The words AND, OR and NOT may confuse the search; try adding quotes: "doi ((chieu sang) or (chieu sach)) - hanh doanh cua thong cong tinh ((toan cao) OR (toan ban))~".
• Adding a wildcard symbol may retrieve word variants: doi ((chieu sang) or (chieu sach)) - hanh doanh cua thong cong tinh ((toan cao) OR (toan ban))*.
