• If you are trying to use Boolean operators, they must be ALL CAPS: lang yan ((tan hua) OR (tuan hua)) jie zhang kim ((song von) OR (doing von)) ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "lang yan ((tan hua) or (tuan hua)) jie zhang kim ((song von) OR (doing von)) ;~".
• Adding a wildcard symbol may retrieve word variants: lang yan ((tan hua) or (tuan hua)) jie zhang kim ((song von) OR (doing von)) ;*.
