Perhaps you should try some spelling variations:
mohan rai » milan rai, mohan r
mohon roy » cohen roy, mon roy
p mohana » _ mohan
p mohan » _ mohan, r mohan, b mohan
o mohon » _ mohonk
raja p » kraja p, raja _, raja j
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 p mohana rao ) OR ( raja p mohan rai ))) OR ( raja o mohon roy )).
• The words AND, OR and NOT may confuse the search; try adding quotes: "(((( raja p mohana rao ) OR ( raja p mohan rai ))) or ( raja o mohon roy ))".
• Adding a wildcard symbol may retrieve word variants: (((( raja p mohana rao ) OR ( raja p mohan rai ))) or ( raja o mohon roy ))*.
