Perhaps you should try some spelling variations:
reformen im » reformen _, formen im, reformen der
david dang » david ian, david ng
david mant » david ian, david ma, david malone
qiang niu » qiang li
wan you » want you, warn you, can you
qian yi » qian yan
hari » hard, hadi, haji

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 you ((qian yi) OR (qiang niu)) reformen im ((david dang) OR (david mant)) hari ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "wan you ((qian yi) or (qiang niu)) reformen im ((david dang) OR (david mant)) hari ;~".
• Adding a wildcard symbol may retrieve word variants: wan you ((qian yi) or (qiang niu)) reformen im ((david dang) OR (david mant)) hari ;*.
