Perhaps you should try some spelling variations:
"raja ra_ mohan roy" » "raja raj mohan roy", "raja rama mohan roy", "raja raja mohan roy", "raja ra_ mohon roy", "raja ra_ mohan r", "raja ra_ mohan rai", "raja ravi mohan roy", "raja _ mohan roy", "raja r mohan roy"
"raja ram mohan roy" » "raja ram mohon roy", "raja ram mohan r", "raja ram mohan rai", "raja r mohan roy", "raja ravi mohan roy", "raja roy mohan roy", "raja ra_ mohan roy", "raja rar mohan roy", "raja rab mohan roy"
"raja m mohan roy" » "raja m mohon roy", "raja m mohan r", "raja m mohan rai", "raja _ mohan roy", "raja r mohan roy", "raja b mohan roy", "raja j mohan roy"

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 ra_ mohan roy") OR ("raja ram mohan roy"))) OR ("raja m mohan roy")).
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"raja ra_ mohan roy\") OR (\"raja ram mohan roy\"))) or (\"raja m mohan roy\"))".
• Removing quotes may allow a broader search: (((( raja ra_ mohan roy ) OR ( raja ram mohan roy ))) or ( raja m mohan roy )).
• Adding a wildcard symbol may retrieve word variants: (((("raja ra_ mohan roy") OR ("raja ram mohan roy"))) or ("raja m mohan roy"))*.
