Haystack tweaks for Django 1.7.7. I had to upgrade to Haystack 2.3.1 to get it to work with Django 1.7.7. I also had to update the Xapian backend. But I ran into problems. On my laptop anyway (Ubuntu 14.0.4), xapian gets mad when search terms are greater than 245 chars (or something) when indexing. So I created a custom field that would simply omit terms greater than 64 chars and used this field everywhere I previously used a CharField. Secondly, the custom search form was broken now. Something changed in the Xapian backend and exact searches stopped working. Fortunately the auto_query (which I was using originally and broke during an upgrade) started working again. So I cut the search form back over to doing an auto_query. I kept the form the same (3 fields) because I didn't want to change the form and I think it's better that way.

"""Haystack search index for the news application."""
from haystack import indexes

from custom_search.fields import MaxTermSizeCharField
from news.models import Story


class StoryIndex(indexes.SearchIndex, indexes.Indexable):
    text = MaxTermSizeCharField(document=True, use_template=True)
    author = indexes.CharField(model_attr='submitter')
    pub_date = indexes.DateTimeField(model_attr='date_submitted')

    def get_model(self):
        return Story

    def get_updated_field(self):
        return 'update_date'
