[elephant-devel] strings as Class Indices ?

[franks-muc at web.de]

I wonder if it is possible to use strings in class indices. The example from the manual 
using integers works well on my computer (windows,acl-trial,elephant,postgres). 
I modified this example to use strings:

(defclass idx-four ()
  ((slot1 :initarg :slot1 :accessor slot1 :index t))
  (:metaclass persistent-metaclass))


(defun make-idx-four (val)
  (make-instance 'idx-four :slot1 val))

(with-transaction ()
  (mapc #'make-idx-four '("1" "1" "1" "2" "2" "4" "5" "5" "5" "6" "10")))

(get-instances-by-value 'idx-four 'slot1 "1")
 ==> NIL

I suspect that nil is not the desired result since other examples provided 
for elephant suggest that strings should work (see (get-instance-by-value 'user 'name name)
in http://common-lisp.net/pipermail/elephant-devel/2006-July/000477.html).

Could someone please explain where I am wrong ?
Thank you in advance!
