Perhaps you should try some spelling variations:
mohan rai » mohana rao, milan rai, mohan r
r mohan » _ mohan
mon roy » von roy, mohon roy, kwon roy
raja r » raja _, raja j, raja m
raja o » raja _, raja j, raja m
raja a » rajan a, rajah a, raja _
o mon » _ mon
a mon » a monk, a mono, a man

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