Hi, I have a problem with django-haystack. According to this tutorial I got this apps: django-haystack xapian-haystack
I set everything but i have this error: django.core.exceptions.ImproperlyConfigured: 'xapian' isn't an available search backend. Available options are: 'dummy', 'solr', 'whoosh'
Why xapian is not available? Thanks for your help.
