Perhaps you should try some spelling variations:
raja harvey » graff harvey
harvey john » hervey john, hartley john
john roe » john rose, john rowe, john rolle
kwon roy » kwon o, kwon go, kwon ho
mon roy » von roy, mohon roy
raja r » raja j, raja m
r kwon » _ kwon, o kwon, c kwon

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: (( raja harvey john roe ) OR ((( raja _ mon roy ) OR ( raja r kwon roy ))))*.
