Perhaps you should try some spelling variations:
changed won » changed john, chang won, changed world
19 changed » _ changed, a changed, 9 changes
yang yang » wang yang, wang yan
shang hai » shang kai, dang hai, chang ha
yan yang » yao yang, dan yang, tan yang
wong yue » wang yue, hong yu
judy 19 » judy 1952, judy 1953, study 19
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) OR (yang yang)) judy 19 changed won ((shang hai) OR (wong yue)) ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "wang ((yan yang) OR (yang yang)) judy 19 changed won ((shang hai) or (wong yue)) ;~".
• Adding a wildcard symbol may retrieve word variants: wang ((yan yang) OR (yang yang)) judy 19 changed won ((shang hai) or (wong yue)) ;*.
