Perhaps you should try some spelling variations:
"raja m cohen roy" » "raja m cohen jody", "raja m cohen guy", "raja _ cohen roy", "raja b cohen roy", "raja p cohen roy", "raja r cohen roy"
"raja j cohen roy" » "raja j cohen jody", "raja j cohen guy", "raja _ cohen roy", "raja r cohen 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"

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