• If you are trying to use Boolean operators, they must be ALL CAPS: doi ((chieu sach) OR (chieu sang)) - hanh chinh quan nhung huong dan ((than cau) OR (toan ban))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "doi ((chieu sach) OR (chieu sang)) - hanh chinh quan nhung huong dan ((than cau) or (toan ban))~".
• Adding a wildcard symbol may retrieve word variants: doi ((chieu sach) OR (chieu sang)) - hanh chinh quan nhung huong dan ((than cau) or (toan ban))*.
