Perhaps you should try some spelling variations:
mohon roy » mon roy
cohen roy » cohen jody, cohen guy
kwon ho » kwon o, koon ho, kwon go
raja m » raja _, raja j, raja r
raja o » raja _, raja j, raja r
o kwon » _ 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 m ((mohon roy) OR (cohen roy)) ) OR ( raja o kwon ho ))*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "(( raja m ((mohon roy) OR (cohen roy)) ) or ( raja o kwon ho ))*".
