Perhaps you should try some spelling variations:
"raja r mohana rao" » "raja r mohan rai", "raja r mohan rao", "raja p mohana rao", "raja k mohana rao", "raja _ mohana rao", "raja j mohana rao", "raja m mohana rao"
"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 rob", "raja 1 von roh", "raja _ von roy", "raja j von roy", "raja m von roy", "raja 2 von 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 _am mohan r") OR ("raja r mohana rao"))) OR ("raja 1 von roy"))*.
• Removing quotes may allow a broader search: (((( raja _am mohan r ) or ( raja r mohana rao ))) or ( raja 1 von roy ))*.
