Perhaps you should try some spelling variations:
reformen a » reformen _, reformen 2, reformen f
reformen 6 » reformen _, reformen 2, reformen f
what you » what do
warn you » earn your, can you, when you
xian der » van der, man der, pian del
david ng » david g, david n, david a
ng ghi » hong ghi

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: ((what you) OR (warn you)) xian der ((reformen a) OR (reformen 6)) david ng ghi ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((what you) or (warn you)) xian der ((reformen a) OR (reformen 6)) david ng ghi ;~".
• Adding a wildcard symbol may retrieve word variants: ((what you) or (warn you)) xian der ((reformen a) OR (reformen 6)) david ng ghi ;*.
