FIX FOR THIS BUG:
Make a small change to server\openerp\addons\base\res\res_partner.py:
Line 358 - change the search operator used to find matches.
ORIGINAL: ids = self.search(cr, user, [('zip','=',name)] + args, limit=limit, context=context)
CHANGE: ids = self.search(cr, user, [('zip',operator,name)] + args, limit=limit, context=context)
