Perhaps you should try some spelling variations:
mohan rai » mohana rao, milan rai, mohan r
mohon roy » cohen roy, mon roy
r mohan » _ mohan
o mohon » _ mohonk
raja r » raja _, raja j, raja m
raja o » 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 r mohan rai ) OR ( raja o mohon roy )).
• Adding a wildcard symbol may retrieve word variants: (( raja r mohan rai ) or ( raja o mohon roy ))*.
