Perhaps you should try some spelling variations:
thing lens » thin lens, thing leads, nothing less
yan klang » den klang, yan clan, yan liang
died last » die last
lens dong » jeng dong
dong sign » dong sin, among sign, dong bin
der last » deck last, over last, der lage
wang » wing, wan

You may be able to get more results by adjusting your search query.

• Performing a fuzzy search may retrieve terms with similar spellings: (wang or lang) yan klang ((die lage) or (((died last) OR (der last)))) thing lens dong sign ;~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (wang OR lang) yan klang ((die lage) OR (((died last) OR (der last)))) thing lens dong sign ;*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "(wang or lang) yan klang ((die lage) or (((died last) OR (der last)))) thing lens dong sign ;*".
