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