Perhaps you should try some spelling variations:
mohan roy » mohan r, mohan rai, roman roy
mohon roy » cohen roy, mon roy
raja ram » raja ravi, raja m, raja r
m mohon » m mohan, m morton, _ mohonk
m moxon » mr moxon, j moxon, m oxon

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