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