wang jing » wang ning, wang liang, wang yang
song hong » song chong, hong hong, kong hong
hong wong » hong kong, hong jong, hong hong

• If you are trying to use Boolean operators, they must be ALL CAPS: (((wang OR wan) yan) OR (huang cheng)) ((wang jing) OR (yang liang)) li song hong wong sau ;~.
• Adding a wildcard symbol may retrieve word variants: (((wang or wan) yan) or (huang cheng)) ((wang jing) or (yang liang)) li song hong wong sau ;*.
