Perhaps you should try some spelling variations:
reformen levi » reformen bei, reformen vi, reformen der
anhang der » anhand der, anhang dr, anhang die
levi david » levine david, maleki david
zhang der » zwang der, zugang der, gang der
wing yan » wang yan, wing ian, wing tan
qian yan » qian jun, qian yi

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: ((wing yan) OR (qian yan)) ((zhang der) OR (anhang der)) reformen levi david a w ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((wing yan) or (qian yan)) ((zhang der) OR (anhang der)) reformen levi david a w ;~".
• Adding a wildcard symbol may retrieve word variants: ((wing yan) or (qian yan)) ((zhang der) OR (anhang der)) reformen levi david a w ;*.
