Perhaps you should try some spelling variations:
mohan roy » mohan r, mohan rai, roman roy
mohon roy » cohen roy, mon roy
am mohan » ram mohan, m mohan, rama mohan
raja r » raja _
raja j » raja _
raja m » raja _

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) OR (raja j))am mohan roy\") or (\"((raja m) OR (((raja r) OR (raja j)))) mohon roy\"))".
• The words AND, OR and NOT may confuse the search; try adding quotes: "\"((\\"((raja r) OR (raja j))am mohan roy\\") or (\\"((raja m) or (((raja r) OR (raja j)))) mohon roy\\"))\"".
• Removing quotes may allow a broader search: (( ((raja r) OR (raja j))am mohan roy ) or ( ((raja m) or (((raja r) OR (raja j)))) mohon roy )).
