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 j mohan rai", "raja p mohana rao", "raja k mohana rao", "raja _ mohanad rao", "raja _ mohana rao"
"raja m mohon roy" » "raja m cohen roy", "raja m mon roy", "raja m mohan roy", "raja m moxon roy", "raja m morton roy", "raja _ 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 j mohana rao"))) OR ("raja m mohon roy")).
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"raja r mohana rao\") OR (\"raja j mohana rao\"))) or (\"raja m mohon roy\"))".
• Removing quotes may allow a broader search: (((( raja r mohana rao ) OR ( raja j mohana rao ))) or ( raja m mohon roy )).
• Adding a wildcard symbol may retrieve word variants: (((("raja r mohana rao") OR ("raja j mohana rao"))) or ("raja m mohon roy"))*.
