ElasticSearch DocumentMissingException

'm using django-haystack with elasticsearch.

I have a problem when i'm using the "more like this" functionality

here is what I doing:

--- from haystack.query import SearchQuerySet
--- from appl.models import Product
--- p = Product.objects.all()[0]
--- p
[Product: Windows 8]

--- p.pk
207

--- SearchQuerySet().models(Product).filter(django_id=207)
PUT /lang-en [status:400 request:0.110s]
[SearchResult: appl.product (pk='207')]

--- SearchQuerySet().models(Product).more_like_this(p)
[]
GET /lang-en/modelresult/appl.product.207/_mlt?mlt_fields=text&search_from=0&search_size=20 [status:404 request:0.102s]
Failed to fetch More Like This from Elasticsearch for document 'appl.product.207': TransportError(404, 'DocumentMissingException[[_na][_na] [modelresult][appl.product.207]: document missing]')

It says that document "appl.product.207" does not exists , but when I use a filter , it returns me the object

[SearchResult: appl.product (pk='207')]

maybe I'm doing something wrong?

Start with SearchQuerySet().models(Product).more_like_this(p) and compare its Elasticsearch request with the preceding django_id filter. Reproduce the 404 for /modelresult/appl.product.207/_mlt and check why the document is visible to filtering but missing from More Like This. Done means the cause is identified and the reported More Like This behavior is corrected or clearly documented.
