I have some simple perl code that does that sort of thing but I cheat
somewhat, I parse the above into something like:-

eval q{($s eq 'escort' || $s eq 'ford') &&  !($s eq 'estuary' || $s eq
'brook' || $s  eq 'erotic services')}

in fact, in my case, some of these become $s =~ /escort/ or some near
equivalent.

Does my job.
