Perhaps you should try some spelling variations:
mohan roy » mohan r, mohan rai, roman roy
mohon roy » cohen roy, mon roy
raja ram » raja ravi
m mohon » m mohan, m moxon, m morton
raja r » raja _, raja j
raja m » 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) OR (raja r))) OR (raja roy)) mohan roy\") or (\"raja m mohon roy\"))".
• The words AND, OR and NOT may confuse the search; try adding quotes: "\"((\\"((((raja ram) OR (raja r))) or (raja roy)) mohan roy\\") or (\\"raja m mohon roy\\"))\"".
• Removing quotes may allow a broader search: (( ((((raja ram) OR (raja r))) or (raja roy)) mohan roy ) or ( raja m mohon roy )).
