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