• If you are trying to use Boolean operators, they must be ALL CAPS: ho chieu sach - ((hanh manh) OR (hanh mang)) hua khong cong ((san tran) OR (ban tran)) cao.
• The words AND, OR and NOT may confuse the search; try adding quotes: "ho chieu sach - ((hanh manh) or (hanh mang)) hua khong cong ((san tran) OR (ban tran)) cao".
• Adding a wildcard symbol may retrieve word variants: ho chieu sach - ((hanh manh) or (hanh mang)) hua khong cong ((san tran) OR (ban tran)) cao*.
