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 m, raja roy
mohan r » mohan _, mohan j, mohan k
r mohon » r mohan, _ mohonk, r morton
raja r » raja _, raja j, raja m

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 r mohon roy )).
• The words AND, OR and NOT may confuse the search; try adding quotes: "(( raja ram ((mohan roy) OR (mohan r)) ) or ( raja r mohon roy ))".
• Adding a wildcard symbol may retrieve word variants: (( raja ram ((mohan roy) OR (mohan r)) ) or ( raja r mohon roy ))*.
