• If you are trying to use Boolean operators, they must be ALL CAPS: ho chieu sach - ((thanh hang) OR (tranh hang)) ((cua phuong) OR (cuc phuong)) huong ban than cau~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "ho chieu sach - ((thanh hang) or (tranh hang)) ((cua phuong) OR (cuc phuong)) huong ban than cau~".
• Adding a wildcard symbol may retrieve word variants: ho chieu sach - ((thanh hang) or (tranh hang)) ((cua phuong) OR (cuc phuong)) huong ban than cau*.
