Perhaps you should try some spelling variations:
changed john » change john, changed our, changed post
chasse john » change john, class john, chassama john
yang data » ring data, yang dali, yang maha
data when » drama when, data what, data we
yan yang » yang yang, yao yang, dan yang
kong siu » kong eiu, wong siu, dong sin
wan yan » wang yan, nan yan, wai yan

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 yang data when ((chasse john) OR (changed john)) kong siu ;~.
• Adding a wildcard symbol may retrieve word variants: wan yan yang data when ((chasse john) or (changed john)) kong siu ;*.
