Perhaps you should try some spelling variations:
ram mohan » r mohan
mohon roy » cohen roy, mon roy
raja ram » raja ravi, raja roy
mohan r » mohan _, mohan j, mohan k
raja m » raja _, raja j
raja r » raja _, raja j

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 ram mohan r\") or (\"((raja m) OR (raja r)) mohon roy\"))".
• Removing quotes may allow a broader search: (( raja ram mohan r ) or ( ((raja m) or (raja r)) mohon roy )).
