Perhaps you should try some spelling variations:
mohon roy » cohen roy
m mohan » _ mohan, r mohan, b mohan
mohan r » mohan _, mohan j, mohan k
mon roy » von roy, kwon roy
raja m » raja j, raja r
raja a » rajan a, rajah a, raja j
a mon » a monk, a mono, a man

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 mohan r ) OR ((( raja _ mohon roy ) OR ( raja a mon roy )))).
• Adding a wildcard symbol may retrieve word variants: (( raja m mohan r ) or ((( raja _ mohon roy ) or ( raja a mon roy ))))*.
