Perhaps you should try some spelling variations:
"raja b mohan roy" » "raja b mohon roy", "raja b mohan r", "raja b mohan rai", "raja _ mohan roy", "raja r mohan roy", "raja b mocan roy", "rajal b mohan roy", "raja j mohan roy"
"raja ravi mon roy" » "raja ravi n roy", "raja ravi von roy", "raja ravi mohon roy", "raja ravi kwon 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 ravi mon roy") OR ("raja b mohan roy")).
• Removing quotes may allow a broader search: (( raja ravi mon roy ) or ( raja b mohan roy )).
• Adding a wildcard symbol may retrieve word variants: (("raja ravi mon roy") or ("raja b mohan roy"))*.
