Perhaps you should try some spelling variations:
"raja ram mohan roy" » "raja r mohan roy", "raja ram mohon roy", "raja ram mohan r", "raja ram mohan rai", "raja ravi mohan roy", "raja m mohan roy"
"raja o kwon roy" » "raja o kwon o", "raja o kwon go", "raja o kwon ho", "raja j kwon roy", "raja m kwon roy", "raja r kwon roy", "raja _ kwon roy"
"raja o mon roy" » "raja o von roy", "raja o mohon roy", "raja j mon roy", "raja m mon roy", "raja r mon roy", "raja a mon roy"
"raja _ mon roy" » "raja _ von roy", "raja _ mohon 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 ram mohan roy") OR ((((("raja o mon roy") OR ("raja o kwon roy"))) OR ("raja _ mon roy")))).
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"raja ram mohan roy\") or (((((\"raja o mon roy\") OR (\"raja o kwon roy\"))) or (\"raja _ mon roy\"))))".
• Removing quotes may allow a broader search: (( raja ram mohan roy ) or ((((( raja o mon roy ) OR ( raja o kwon roy ))) or ( raja _ mon roy )))).
• Adding a wildcard symbol may retrieve word variants: (("raja ram mohan roy") or ((((("raja o mon roy") OR ("raja o kwon roy"))) or ("raja _ mon roy"))))*.
