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, raja r
raja roy » raja r
raja m » raja _, raja r
raja j » raja _, raja r

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