Perhaps you should try some spelling variations:
mohon roy » cohen roy, mon roy
koon ho » joon ho, kwon ho, yoon ho
raja m » raja _, raja r
raja j » raja _, raja r
raja o » raja _, raja r, raja g
o koon » o kwon, _ koon, k koon

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) OR (raja j)) mohon roy ) OR ( raja o koon ho ))*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "(( ((raja m) OR (raja j)) mohon roy ) or ( raja o koon ho ))*".
