Perhaps you should try some spelling variations:
"raja ravi mohan r" » "raja rajiv mohan r", "raja hari mohan r", "raja ram mohan r", "raja ravi mohan _", "raja ravi mohan j", "raja ravi mohan k"
"raja b mohan _oy" » "raja b mohan _", "raja _ mohan _oy", "raja r mohan _oy", "raja b mocan _oy", "rajal b mohan _oy", "raja j mohan _oy"

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 ravi mohan r") OR ("raja b mohan _oy")).
• Removing quotes may allow a broader search: (( raja ravi mohan r ) or ( raja b mohan _oy )).
• Adding a wildcard symbol may retrieve word variants: (("raja ravi mohan r") or ("raja b mohan _oy"))*.
