Perhaps you should try some spelling variations:
"raja r mohan rai" » "raja r mohana rao", "raja r milan rai", "raja r mohan r", "raja j mohan rai", "raja m mohan rai"
"raja _ mohan rai" » "raja _ mohana rao", "raja _ milan rai", "raja _ mohan r"
"raja o von rob" » "raja o von robo", "raja o von rom", "raja o von roh", "raja j von rob", "raja m von rob", "raja g von rob", "raja _ von rob", "raja 2 von rob", "raja 1 von rob"

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 _ mohan rai"))) OR ("raja o von rob")).
• Removing quotes may allow a broader search: (((( raja r mohan rai ) or ( raja _ mohan rai ))) or ( raja o von rob )).
• Adding a wildcard symbol may retrieve word variants: (((("raja r mohan rai") or ("raja _ mohan rai"))) or ("raja o von rob"))*.
