Perhaps you should try some spelling variations:
logic changes » ionic changes, luc changes
changes bei » changes being, changes b, changes big
bei daten » bei den, der daten, ii daten
yang jin » yang jie, yang jun, ying jin
wang wei » zhang wei, wang zhi
wang li » wang lei, wang lin, tang li
lang » land, long

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: lang logic changes bei daten ((wang li) OR (yang jin)) ((wang wei) OR (meng xin)) ;~.
• Adding a wildcard symbol may retrieve word variants: lang logic changes bei daten ((wang li) or (yang jin)) ((wang wei) or (meng xin)) ;*.
