Perhaps you should try some spelling variations:
mohon roy » cohen roy, mon roy
john roy » john ray, john rob, john leroy
john roe » john rose, john rowe, john rolle
o mohon » _ mohonk
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 carey ((john roy) OR (john roe)) ) OR ( raja o mohon roy )).
• The words AND, OR and NOT may confuse the search; try adding quotes: "(( raja carey ((john roy) OR (john roe)) ) or ( raja o mohon roy ))".
• Adding a wildcard symbol may retrieve word variants: (( raja carey ((john roy) OR (john roe)) ) or ( raja o mohon roy ))*.
