      raise TemplateDoesNotExist(', '.join(template_name_list), chain=chain)
  django.template.exceptions.TemplateDoesNotExist: search/indexes/posts/post_text.txt

also heres my settings.py

WHOOSH_INDEX = os.path.join(BASE_DIR, 'whoosh/')


HAYSTACK_CONNECTIONS = {
    'default': {
        'ENGINE': 'haystack.backends.whoosh_backend.WhooshEngine',
        'PATH': WHOOSH_INDEX,
    },
}

i'm not sure what exactly is going on. any help as welcomed. Ive been trying to tinker with it but I havent found out exaclty what it is. also I don't see haystack in my site packages like it shows in the paths above

EDIT: I added a post directory inside of indexes and then put post_text.txt inside of it. then the errors went away but now nothing is being returned but it's like an invisibble list is pushing on my css. What's going on here?

In the terminal I'm getting messages like 

Model could not be found for SearchResult '<SearchResult: posts.post (pk='20')>'.
Model could not be found for SearchResult '<SearchResult: posts.post (pk='20')>'.
[02/Feb/2016 15:34:11] "POST /posts/search/ HTTP/1.1" 200 32

This is simply because use_template=True in your search_indexes.py

make it use_template=False

otherwise, you have to specify your template.

The result of your query is a set of SearchResult objects so, you have to get the model objects.

something like this

sqs = SearchQuerySet().models(Model).load_all().auto_query(query)
orm_objects = orm_objects.filter(pk__in=sqs.values_list('pk', flat=True))
return orm_objects
