• If you are trying to use Boolean operators, they must be ALL CAPS: ho ((chieu sach) OR (chiet tach)) - hanh trang cua thong cong dang ((thanh chau) OR (thanh cha))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "ho ((chieu sach) or (chiet tach)) - hanh trang cua thong cong dang ((thanh chau) OR (thanh cha))~".
• Adding a wildcard symbol may retrieve word variants: ho ((chieu sach) or (chiet tach)) - hanh trang cua thong cong dang ((thanh chau) OR (thanh cha))*.
