Perhaps you should try some spelling variations:
ravi mohan » rajiv mohan, hari mohan, ram mohan
mohan rai » mohana rao, milan rai, mohan r
mon roy » mohon roy, kwon roy
von roy » von rom, von rob, von roh
raja a » rajan a, rajah a, raja _

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 ravi mohan rai ) OR ( raja a ((mon roy) OR (von roy)) ))*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "(( raja ravi mohan rai ) or ( raja a ((mon roy) OR (von roy)) ))*".
