Perhaps you should try some spelling variations:
changed john » change john, changed our, changed post
l changed » _ changed, a changed, 19 changed
shang hai » dang hai, chang ha, hong hai
yan yang » yang yang, yao yang, dan yang
wong yue » wang yue, hong yu
wang » wing, wan, lang
judy » july

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 judy l changed john ((((shang hai) OR (shang kai))) OR (wong yue)) ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "wang yan yang judy l changed john ((((shang hai) OR (shang kai))) or (wong yue)) ;~".
• Adding a wildcard symbol may retrieve word variants: wang yan yang judy l changed john ((((shang hai) OR (shang kai))) or (wong yue)) ;*.
