Perhaps you should try some spelling variations:
mohan roy » mohan r, roman roy, rammohan roy
mohan rai » mohana rao, milan rai, mohan r
mohon roy » mon roy
cohen roy » cohen jody, cohen guy
raja ram » raja ravi, raja r, raja roy
raja m » raja _, raja j, 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 ram ((mohan roy) OR (mohan rai)) ) OR ( raja m ((mohon roy) OR (cohen roy)) )).
• The words AND, OR and NOT may confuse the search; try adding quotes: "(( raja ram ((mohan roy) or (mohan rai)) ) or ( raja m ((mohon roy) OR (cohen roy)) ))".
• Adding a wildcard symbol may retrieve word variants: (( raja ram ((mohan roy) or (mohan rai)) ) or ( raja m ((mohon roy) OR (cohen roy)) ))*.
