• If you are trying to use Boolean operators, they must be ALL CAPS: ho ((chieu sach) OR (chieu sang)) - thanh trung ((cua thong) OR (cua khong)) cong van khanh cu.
• The words AND, OR and NOT may confuse the search; try adding quotes: "ho ((chieu sach) OR (chieu sang)) - thanh trung ((cua thong) or (cua khong)) cong van khanh cu".
• Adding a wildcard symbol may retrieve word variants: ho ((chieu sach) OR (chieu sang)) - thanh trung ((cua thong) or (cua khong)) cong van khanh cu*.
