move using » done using
wang ryan » wang yan, wang yang, wang ban
among sar » among hard, kong sar, among sex

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: ((move using) OR (wang ryan)) ya hua risk ((sharing risk) OR (trading risk)) among sar ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((move using) or (wang ryan)) ya hua risk ((sharing risk) OR (trading risk)) among sar ;~".
• Adding a wildcard symbol may retrieve word variants: ((move using) or (wang ryan)) ya hua risk ((sharing risk) OR (trading risk)) among sar ;*.
