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