Perhaps you should try some spelling variations:
reformen teil » reformen bei, reformen beim, reformen der
teil david » weil david, fell david
liang wei » xiang wei, zhang wei, wang wei
qian yan » qian jun, qian yi
wan yan » wang yan, nan yan, wang yang
wai yan » wang yan, wei yang
david g » david a, david _, david k

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 yan) OR (wai yan))) OR (qian yan)) ((wang zhi) OR (liang wei)) reformen teil david g g ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((wan yan) OR (wai yan))) or (qian yan)) ((wang zhi) or (liang wei)) reformen teil david g g ;~".
• Adding a wildcard symbol may retrieve word variants: ((((wan yan) OR (wai yan))) or (qian yan)) ((wang zhi) or (liang wei)) reformen teil david g g ;*.
