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