Perhaps you should try some spelling variations:
changed john » changed our, changed post, changed rome
change john » chasse john, change japan, channon john
yang java » yang maha
java when » data when
yan yang » yang yang, yao yang, dan yang
kong siu » kong eiu, dong sin, kong sar
wong siu » wong shiu, wong sau, wong siew
wang » wing, wan, lang

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: wang yan yang java when ((change john) OR (changed john)) ((kong siu) OR (wong siu)) ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "wang yan yang java when ((change john) or (changed john)) ((kong siu) OR (wong siu)) ;~".
• Adding a wildcard symbol may retrieve word variants: wang yan yang java when ((change john) or (changed john)) ((kong siu) OR (wong siu)) ;*.
