Perhaps you should try some spelling variations:
formen die » formel die, former die, reformen die
wan ylang » wang yang, dan yang
di formen » die formen, ii formen, i formen
tan yang » dan yang, tan ying, tan yong
wang di » yang di, wang d, wang li
david n » david a, david _, david g
david k » david a, david _

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: ((wan ylang) OR (tan yang)) wang di formen die ((david n) OR (david k)) hai ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((wan ylang) or (tan yang)) wang di formen die ((david n) OR (david k)) hai ;~".
• Adding a wildcard symbol may retrieve word variants: ((wan ylang) or (tan yang)) wang di formen die ((david n) OR (david k)) hai ;*.
