Perhaps you should try some spelling variations:
mohan rai » mohana rao, milan rai, mohan r
kwon roy » kwon o, kwon go, kwon ho
r mohan » _ mohan
mon roy » von roy, mohon roy
raja r » raja j, raja m
raja o » raja j, raja m, raja g

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 (kwon roy)) ) OR ( raja _ ((mon roy) OR (kwon roy)) ))))*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "(( raja r mohan rai ) or ((( raja o ((mon roy) OR (kwon roy)) ) or ( raja _ ((mon roy) OR (kwon roy)) ))))*".
