• If you are trying to use Boolean operators, they must be ALL CAPS: ho chieu sach - thanh trung nam thang ((nong toan) OR (nong tan)) ((thanh cau) OR (thanh chau))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "ho chieu sach - thanh trung nam thang ((nong toan) or (nong tan)) ((thanh cau) OR (thanh chau))~".
• Adding a wildcard symbol may retrieve word variants: ho chieu sach - thanh trung nam thang ((nong toan) or (nong tan)) ((thanh cau) OR (thanh chau))*.
