Search Suggestions for django elasticsearch - django

Question

I am using the Django Elasticsearch DSL library in order to integrate django with elasticsearch.
I have the search working properly and I am trying to also add the suggestions feature.
my documents.py is the following
# Name of the Elasticsearch index
INDEX = Index('search_movies')
# See Elasticsearch Indices API reference for available settings
INDEX.settings(
number_of_shards=1,
number_of_replicas=1
)
html_strip = analyzer(
'html_strip',
tokenizer="standard",
filter=["standard", "lowercase", "stop", "snowball"],
char_filter=["html_strip"]
)
#INDEX.doc_type
class MovieDocument(DocType):
"""Movie Elasticsearch document."""
id = fields.IntegerField(attr='id')
title = fields.StringField(
analyzer=html_strip,
fields={
'raw': fields.KeywordField(),
'suggest': fields.CompletionField(),
}
)
summary = fields.StringField(
analyzer=html_strip,
fields={
'raw': fields.KeywordField(),
}
)`
I have added the 'suggest': fields.CompletionField(), as I saw it is required in order to get suggestions for that field.
I am trying then to use something similar as to what is shown here. So in my views.py i have the following
client = Elasticsearch()
search_in_title = 'search term goes here'
sreq = Search().using(client).query("multi_match", query=search_in_title, fields=['title', 'summary'])
ssug = sreq.suggest('title_suggestions', search_in_title, term={'field': 'title'})
but the ssug is always empty, so i am guessing i am using it the wrong way.

Answer 1

You need to reference the title.suggest sub-field instead:
ssug = s.suggest('title_suggestions', search_in_title, term={'field': 'title.suggest'})
