Perhaps you should try some spelling variations:
done using » line using, move using
wang yang » wang liang, wang yanling
congo war » congo what, congo a, congo can
best yan » best damn, best way, best run
cong sar » kong sar, cong shu, cong sun
yan jiu » yang jie, yang jin, pang jiu
ya a » a a, y a, ye a

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: ((done using) OR (((wang yang) OR (wang yan)))) ya a best yan jiu ((cong sar) OR (congo war)) ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((done using) or (((wang yang) or (wang yan)))) ya a best yan jiu ((cong sar) OR (congo war)) ;~".
• Adding a wildcard symbol may retrieve word variants: ((done using) or (((wang yang) or (wang yan)))) ya a best yan jiu ((cong sar) OR (congo war)) ;*.
