• Performing a fuzzy search may retrieve terms with similar spellings: ho ((chieu sach) OR (chieu sang)) - hanh trang hua khong cong san ((phan cau) or (than cap))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: ho ((chieu sach) OR (chieu sang)) - hanh trang hua khong cong san ((phan cau) OR (than cap)).
• The words AND, OR and NOT may confuse the search; try adding quotes: "ho ((chieu sach) OR (chieu sang)) - hanh trang hua khong cong san ((phan cau) or (than cap))".
• Adding a wildcard symbol may retrieve word variants: ho ((chieu sach) OR (chieu sang)) - hanh trang hua khong cong san ((phan cau) or (than cap))*.
