Perhaps you should try some spelling variations:
"raja _am mohan _ai" » "raja ram mohan _ai", "raja rama mohan _ai", "raja _ mohan _ai", "raja _am mohan rai", "raja _am mohan _", "raja _a_ mohan _ai", "raja _ar mohan _ai", "raja _ab mohan _ai"
"raja m mohan r" » "raja _ mohan r", "raja r mohan r", "raja b mohan r", "raja m mohan _", "raja m mohan j", "raja m mohan k", "raja j mohan r"
"raja o von roy" » "raja o von rom", "raja o von rob", "raja o von roh", "raja _ von roy", "raja j von roy", "raja r von roy", "raja 2 von roy", "raja 1 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 _ai") OR ("raja m mohan r"))) OR ("raja o von roy"))*.
• Removing quotes may allow a broader search: (((( raja _am mohan _ai ) or ( raja m mohan r ))) or ( raja o von roy ))*.
