Perhaps you should try some spelling variations:
"raja ra_ mohan roy" » "raja ram mohan roy", "raja raj mohan roy", "raja rama mohan roy", "raja ra_ mohan r", "raja ra_ mohan rai", "raja ra_ roman roy", "raja ravi mohan roy", "raja _ mohan roy", "raja roy mohan roy", "raja _a_ mohan roy", "raja ja_ mohan roy"
"raja m mohon roy" » "raja m mon roy", "raja m mohan roy", "raja m moxon roy", "raja m morton roy", "raja _ mohon roy", "raja j mohon roy"
"raja m cohen roy" » "raja m cohen jody", "raja m cohen guy", "raja _ cohen roy", "raja j cohen roy", "raja p cohen roy"
"raja r cohen roy" » "raja r cohen jody", "raja r cohen guy", "raja _ cohen roy", "raja j cohen roy", "raja p cohen 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 m mohon roy") OR ((("raja m cohen roy") OR ("raja r cohen roy")))))).
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"raja ra_ mohan roy\") or (((\"raja m mohon roy\") or (((\"raja m cohen roy\") OR (\"raja r cohen roy\"))))))".
• Removing quotes may allow a broader search: (( raja ra_ mohan roy ) or ((( raja m mohon roy ) or ((( raja m cohen roy ) OR ( raja r cohen roy )))))).
• Adding a wildcard symbol may retrieve word variants: (("raja ra_ mohan roy") or ((("raja m mohon roy") or ((("raja m cohen roy") OR ("raja r cohen roy"))))))*.
