Perhaps you should try some spelling variations:
mohon roy » cohen roy, mon roy
mohan roy » mohan r, mohan rai, roman roy
oy mohan » _ mohan, r mohan, 15 mohan
raja r » raja _, raja m
raja j » raja _, 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) OR (raja j))oy mohan roy ) OR ( ((raja r) OR (raja j)) mohon roy )).
• The words AND, OR and NOT may confuse the search; try adding quotes: "(( ((raja r) OR (raja j))oy mohan roy ) or ( ((raja r) OR (raja j)) mohon roy ))".
• Adding a wildcard symbol may retrieve word variants: (( ((raja r) OR (raja j))oy mohan roy ) or ( ((raja r) OR (raja j)) mohon roy ))*.
