Description

While it's possible to search for fields that don't exist (you'll get 0 hits),
you'll get an exception if you try to sort by a field that has no values. The
exception is this:

if (termEnum.term() == null) {
throw new RuntimeException ("no terms in field " + field);
}

I'll attach a change suggested by Yonik Seeley that removes this exception.

Also, the if-condition above is incomplete anyway, so currently the exception
is not always thrown (as termEnum .term() might well be != null but point to a
term in a different field already)
