Perhaps you should try some spelling variations:
mohan rai » mohana rao, milan rai, mohan r
r mohan » _ mohan
kwon ho » kwon o, kwon go, kwon h
koon ho » joon ho, yoon ho, moon how
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 ((kwon ho) OR (koon ho)) )).
• The words AND, OR and NOT may confuse the search; try adding quotes: "(( raja r mohan rai ) or ( raja o ((kwon ho) OR (koon ho)) ))".
• Adding a wildcard symbol may retrieve word variants: (( raja r mohan rai ) or ( raja o ((kwon ho) OR (koon ho)) ))*.
