Perhaps you should try some spelling variations:
mam mohon » ram mohan
mohon roy » cohen roy, mon roy
raja mam » raja m
kwon ho » kwon o, koon ho, kwon go
raja o » raja _, raja m, raja r
raja j » raja _, raja m, raja r

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