Perhaps you should try some spelling variations:
"raja ravi mohon roy" » "raja ravi cohen roy"
"raja ravi mon roy" » "raja ravi n roy", "raja ravi kwon roy"
"raja vi von roy" » "raja vi von rom", "raja vi von rob", "raja vi von roh"

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 ravi mon roy") OR ("raja ravi mohon roy"))) OR ("raja vi von roy")).
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"raja ravi mon roy\") OR (\"raja ravi mohon roy\"))) or (\"raja vi von roy\"))".
• Removing quotes may allow a broader search: (((( raja ravi mon roy ) OR ( raja ravi mohon roy ))) or ( raja vi von roy )).
• Adding a wildcard symbol may retrieve word variants: (((("raja ravi mon roy") OR ("raja ravi mohon roy"))) or ("raja vi von roy"))*.
