Perhaps you should try some spelling variations:
"raja ravi mohana rao" » "raja rama mohana rao", "raja haji mohanad rao"
"raja ram mohan rai" » "raja r mohan rai", "raja ram milan rai", "raja ram mohan r", "raja m mohan rai", "raja roy mohan rai"
"raja _ mon roy" » "raja _ von roy", "raja _ mohon roy", "raja _ 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 ram mohan rai") OR ("raja ravi mohana rao"))) OR ("raja _ mon roy")).
• Removing quotes may allow a broader search: (((( raja ram mohan rai ) or ( raja ravi mohana rao ))) or ( raja _ mon roy )).
• Adding a wildcard symbol may retrieve word variants: (((("raja ram mohan rai") or ("raja ravi mohana rao"))) or ("raja _ mon roy"))*.
