Perhaps you should try some spelling variations:
mam mohan » ram mohan, rama mohan, jai mohan
raja mam » raja m
mohan j » mohan _, johan j, mohan k
m mohon » m moxon, m morton, _ mohonk
m mohan » _ mohan, r mohan, b mohan

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