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 m mohan rai"
"raja j mohan rai" » "raja j mohana rao", "raja j milan rai", "raja j mohan r", "raja _ mohan rai", "raja b mohan rai", "raja j moran rai", "raja m mohan rai"
"raja o kwon roy" » "raja o kwon o", "raja o kwon go", "raja o kwon ho", "raja _ kwon roy", "raja m kwon roy", "raja g 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 r mohan rai") OR ("raja j mohan rai"))) OR ("raja o kwon roy")).
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"raja r mohan rai\") OR (\"raja j mohan rai\"))) or (\"raja o kwon roy\"))".
• Removing quotes may allow a broader search: (((( raja r mohan rai ) OR ( raja j mohan rai ))) or ( raja o kwon roy )).
• Adding a wildcard symbol may retrieve word variants: (((("raja r mohan rai") OR ("raja j mohan rai"))) or ("raja o kwon roy"))*.
