Perhaps you should try some spelling variations:
mohan roy » mohon roy, mohan r, mohan rai
raja ram » raja ravi, raja m, raja roy
john roy » john ray, john roe, john rob
mon roy » von roy, mohon roy, kwon roy
raja r » 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 ram) OR (raja r)) mon roy ) OR ( ((raja ram) OR (raja r)) john roy ))) OR ( raja _ mohan roy )).
• The words AND, OR and NOT may confuse the search; try adding quotes: "(((( ((raja ram) OR (raja r)) mon roy ) or ( ((raja ram) OR (raja r)) john roy ))) or ( raja _ mohan roy ))".
• Adding a wildcard symbol may retrieve word variants: (((( ((raja ram) OR (raja r)) mon roy ) or ( ((raja ram) OR (raja r)) john roy ))) or ( raja _ mohan roy ))*.
