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