Django Haystack + Elasticsearch - how to return results with a small edit distance from query?

Question

So we are using Django-haystack with the Elasticsearch backend to index a bunch of data for searching. It is very fast and is working great for the most part, but I notice something that I want that seems to be absent. For example, consider the search query "cellar door". I would want a query that is slightly off, like a misspelling, e.g. "cellar dor" or "celar door" to match results for "cellar door". If I try queries like this with our current setup it returns 0 results. I tried using an EdgeNgramField in the search index on the field we wanted to index, but this seems to have absolutely no effect.

Thanks.

you should use Fuzzy query, find example here http://stackoverflow.com/questions/18000714/how-can-i-do-a-fuzzy-search-using-django-haystack-and-the-elasticsearch-backend — Alex, Jul 01 '14 at 15:32

Use suggest to perform spell check.

curl -XPOST 'localhost:9200/index/_search?search_type=count' -d '{

{
   "suggest": {
      "body": {
         "text": "celar door",
         "term": {
            "field": "summary",
            "analyzer": "simple"
         }
      }
   }
}'
