Perhaps you should try some spelling variations:
mohan rai » mohana rao, milan rai
cohen roy » cohen jody, cohen guy
raja ram » raja ravi, raja r, raja roy
mohan r » mohan _, mohan j, mohan k
m cohen » _ cohen, j cohen, b cohen
raja m » raja _, raja j, raja r

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 ((mohan rai) OR (mohan r)) ) OR ( raja m cohen roy )).
• The words AND, OR and NOT may confuse the search; try adding quotes: "(( raja ram ((mohan rai) OR (mohan r)) ) or ( raja m cohen roy ))".
• Adding a wildcard symbol may retrieve word variants: (( raja ram ((mohan rai) OR (mohan r)) ) or ( raja m cohen roy ))*.
