No setting, I think you would have to mess with tsearch2 dictionaries. A
far easier approach is to have your application simply split the words
apart, or even write a wrapper function to do it for you within Postgres, e.g.

CREATE OR REPLACE FUNCTION wordsplit(text) RETURNS text LANGUAGE plperl
AS $_$
my $string = shift;
$string =~ s/\W/ /g;
return $string;
$_$;

SELECT to_tsvector(wordsplit('cat,dog apple/orange'));
