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.
