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 o mohon roy" » "raja o cohen roy", "raja o mon roy", "raja _ mohonk roy", "raja _ mohon roy", "raja j mohon roy", "raja m mohon 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 r mohana rao") OR ("raja o mohon roy")).
• Removing quotes may allow a broader search: (( raja r mohana rao ) or ( raja o mohon roy )).
• Adding a wildcard symbol may retrieve word variants: (("raja r mohana rao") or ("raja o mohon roy"))*.
