Perhaps you should try some spelling variations:
"raja m mohan rai" » "raja m mohana rao", "raja m milan rai", "raja m mohan r", "raja _ mohan rai", "raja r mohan rai", "raja b mohan rai", "raja j mohan rai"
"raja o mohon roy" » "raja o cohen roy", "raja _ mohonk roy", "raja j mohon roy", "raja r mohon roy", "raja g mohon roy"
"raja _ mon roy" » "raja _ von roy", "raja _ kwon roy"

You may be able to get more results by adjusting your search query.

• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"raja m mohan rai\") OR (((\"raja o mohon roy\") OR (\"raja _ mon roy\"))))*".
• Removing quotes may allow a broader search: (( raja m mohan rai ) OR ((( raja o mohon roy ) OR ( raja _ mon roy ))))*.
