Perhaps you should try some spelling variations:
ram mohan » r mohan
mohan roy » mohan r, mohan rai, roman roy
mohon roy » mon roy
cohen roy » cohen jody, cohen guy
raja ram » raja ravi, raja m, raja roy
raja r » raja _, raja j, raja m

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 ( raja r ((mohon roy) OR (cohen roy)) )).
• The words AND, OR and NOT may confuse the search; try adding quotes: "(( raja ram mohan roy ) or ( raja r ((mohon roy) OR (cohen roy)) ))".
• Adding a wildcard symbol may retrieve word variants: (( raja ram mohan roy ) or ( raja r ((mohon roy) OR (cohen roy)) ))*.
