Perhaps you should try some spelling variations:
"raja _ mohan roy" » "raja _ mohon roy", "raja _ mohan r", "raja _ mohan rai"
"raja m moxon roy" » "raja m mohon roy", "raja m mon roy", "raja mr moxon roy", "raja j moxon roy", "raja m oxon roy"
"raja r moxon roy" » "raja r mohon roy", "raja r mon roy", "raja mr moxon roy", "raja j moxon roy", "raja r morton 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 _ mohan roy") OR ((("raja m moxon roy") OR ("raja r moxon roy"))))*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"raja _ mohan roy\") or (((\"raja m moxon roy\") OR (\"raja r moxon roy\"))))*".
• Removing quotes may allow a broader search: (( raja _ mohan roy ) or ((( raja m moxon roy ) OR ( raja r moxon roy ))))*.
