perl compatible (pcre is used as engine) if wildcard=1 in tinrc.

lookahead paterns are supported, so that

group=*
case=0 
score=kill
from=John\s\b(?!Samuelson).*son\b

should work or you could use scooring

give enery article that matches
John\s+.*son\b a score of eg -100
and the ones which match
John\sSamuelson a score of 100
at the end John\sSamuelson gets a score of 0 as he matches both filters
so his articles are "untouched", but the other John *son are killed.

group=*
case=0
score=kill
from=John\s+.*son\b

group=*
case=0 
score=hot
from=John\sSamuelson\b
