My project in on Django 1.9, and haystack doesnt have a compatible release
yet. I was working off master and then I realized that a bunch of boost
support for elasticsearch was being removed. So I backported my project to
1.8 so I could use the 2.4.1 official release to see if I can get Document
and Field boosting working. It seems to me that neither are working.
Here is what I am doing:
from haystack.query import SearchQuerySet, SQ, AutoQuery
search_term = 'C100'
sqs = SearchQuerySet().models(Product).filter(SQ(text=AutoQuery(search_term
)) | SQ(brand_name=search_term) )
for s in sqs:
print s.boost, s.score, s.brand_name, ':', s.object.name
And no matter how I define the indexes the score never changes. Here are
three definitions I am trying and you can see the output of the above code
in the class comment:

The score never changes despite document boost, or field boost against the
non-boosted index. The haystack documentation says this stuff is supported,
and I'm following the documentation example of how to query against boosted
fields. Am I doing something entirely wrong? What else can I try to get
this working?
