Perhaps you should try some spelling variations:
mohon roy » cohen roy, mon roy
am mohan » ram mohan, m mohan, rama mohan
mohan j » mohan _, johan j, mohan k
raja m » raja _, raja j
raja r » raja _, raja j

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