Perhaps you should try some spelling variations:
mohan roy » mohon roy, mohan rai, roman roy
raja ram » raja ravi, raja m, raja r
mohan r » mohan _, mohan j, mohan k
r mohon » _ mohonk, r morton
r mohan » _ mohan

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) OR (r mohan)) 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) OR (r mohan)) roy ))".
• Adding a wildcard symbol may retrieve word variants: (( raja ram ((mohan roy) or (mohan r)) ) or ( raja ((r mohon) OR (r mohan)) roy ))*.
