Cannot get partial word search to work with haystack / elasticsearch

Question

I am trying to get a partial phrase, and I have already addressed the related question , but for some reason my setup does not work. I am using haystack with elasticsearch. Can someone please tell me what I am doing wrong?

class VendorIndex(indexes.SearchIndex, indexes.Indexable): text = indexes.EdgeNgramField(document=True, use_template=True) company_name = indexes.CharField(model_attr='company_name', null=True) def get_model(self): return Vendor def index_queryset(self, using=None): """Used when the entire index for model is updated.""" return self.get_model().objects.all() 

EDIT: I did this job using autocomplete. However, I feel like it's a hack. But here is my code:

 class VendorIndex(indexes.SearchIndex, indexes.Indexable): text = indexes.CharField(document=True, use_template=True) company_name = indexes.CharField(model_attr='company_name', null=True) company_name_auto = indexes.NgramField(model_attr='company_name') def get_model(self): return Vendor def index_queryset(self, using=None): """Used when the entire index for model is updated.""" return self.get_model().objects.all() 

then in the view:

 class SearchVendorView(generics.ListAPIView): serializer_class = serializers.CustomerVendorSerializer def get_queryset(self): results = SearchQuerySet().models(Vendor).autocomplete(company_name_auto=self.request.GET.get('q', '')) vendors = [] for vendor in [result.object for result in results]: vendor.is_liked = Vendor.objects.from_request(self.request).get(pk=vendor.id).user_vote vendors.append(vendor) return vendors

In my case: django-haystack==2.5.1 + elasticsearch==5.0.1 + java elastic search daemon v2.3.1 this is enough to get a partial search:

 from haystack import indexes from authors.models import Author class AuthorIndex(indexes.SearchIndex, indexes.Indexable): text = indexes.EdgeNgramField(document=True, use_template=True) last_name = indexes.CharField(model_attr='last_name') first_name = indexes.CharField(model_attr='first_name') def get_model(self): return Author def index_queryset(self, using=None): """Used when the entire index for model is updated.""" return self.get_model().objects.all() 

And then python manage.py rebuild_index and you can search by:

 from haystack.query import SearchQuerySet SearchQuerySet().filter(content="alex") 

to find Alexander .
