Perhaps you should try some spelling variations:
roman roy » roman army, roman road, roman roig
mohan rai » mohana rao, milan rai, mohan r
raja ram » raja ravi, raja roy
raja m » raja _, raja j
raja r » raja _, raja j

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