There is no such settings.
You can write your parser or dictionary for 'file' token type. We have
howto, see
http://mira.sai.msu.su/~megera/pgsql/ftsdoc/appendixes.html

If you want simple parser, probable better to write one. Probably, the
simple way is to write dictionary, which will return
{apple/orange, apple,orange}.
