Perhaps you should try some spelling variations:
formel die » formen die, former die, forme de
david dang » david ian, david mant, david ng
zwang iii » zugang iii, klang iii
form die » formen die, former die, form der
lang di » yang di, wang di, klang die
wang » wan
zwang » zwan
hai » hadi, haji, hari

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

• If you are trying to use Boolean operators, they must be ALL CAPS: (wang OR wing) yanling ((zwang iii) OR (lang di)) ((form die) OR (formel die)) david dang hai ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "(wang or wing) yanling ((zwang iii) or (lang di)) ((form die) OR (formel die)) david dang hai ;~".
• Adding a wildcard symbol may retrieve word variants: (wang or wing) yanling ((zwang iii) or (lang di)) ((form die) OR (formel die)) david dang hai ;*.
