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