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