python - admin search for generic foreign key django -

i trying put admin search on model in generic foreign key present.

admin.py

class privacysettingsadmin(admin.modeladmin):     fieldsets = (         (none, {             'fields': (                 'field_name',                 'level',              )         }),         (('page/article'), {             'classes': ('grp-collapse grp-open',),             'fields': ('content_type', 'object_id', )         }),     )     autocomplete_lookup_fields = {         'generic': [['content_type', 'object_id']],     }     search_fields = ('object_id',) 

i able search using object_id. want search using feilds of object_id object.
