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