Perhaps you should try some spelling variations:
"raja r mohan rai" » "raja r mohana rao", "raja r milan rai", "raja r mohan _ai", "raja r mohan jai", "raja r mohan kai", "raja _ mohan rai", "raja j mohan rai", "raja m mohan rai"
"raja _am mohan r" » "raja ram mohan r", "raja rama mohan r", "raja _ mohan r", "raja m mohan r", "raja _am mohan _", "raja _am mohan j", "raja _am mohan k"
"raja 1 von roy" » "raja 1 von rom", "raja 1 von roh", "raja 1 mon roy", "raja _ von roy", "raja j von roy", "raja m von roy", "raja 2 von roy"
"raja 1 von rob" » "raja 1 von robo", "raja 1 von rom", "raja 1 von roh", "raja _ von rob", "raja j von rob", "raja m von rob", "raja 2 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 _am mohan r") OR ("raja r mohan rai"))) OR ((("raja 1 von roy") OR ("raja 1 von rob"))))*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"raja _am mohan r\") or (\"raja r mohan rai\"))) or (((\"raja 1 von roy\") OR (\"raja 1 von rob\"))))*".
• Removing quotes may allow a broader search: (((( raja _am mohan r ) or ( raja r mohan rai ))) or ((( raja 1 von roy ) OR ( raja 1 von rob ))))*.
