• If you are trying to use Boolean operators, they must be ALL CAPS: ho ((chieu sang) OR (hieu lang)) - thanh huong ca dung cong ((van than) OR (van thang)) cau.
• The words AND, OR and NOT may confuse the search; try adding quotes: "ho ((chieu sang) OR (hieu lang)) - thanh huong ca dung cong ((van than) or (van thang)) cau".
• Adding a wildcard symbol may retrieve word variants: ho ((chieu sang) OR (hieu lang)) - thanh huong ca dung cong ((van than) or (van thang)) cau*.
