Elasticstack Mapping issue with elastic search 2.3.2

[X17]

I have tried every step from documentation:
But have not been able to achieve mapping via elastic stack. when i try

./manage.py rebuild_index

In sense terminal :

GET haystack/_settings

{
   "haystack": {
      "settings": {
         "index": {
            "creation_date": "1462163781086",
            "number_of_shards": "1",
            "number_of_replicas": "1",
            "uuid": "A4pRJ-qISlOOxcsYNqZwvg",
            "version": {
               "created": "2030199"
            }
         }
      }
   }
}

If I try mapping using Sense chrome extension:

GET haystack/_settings

{
   "haystack": {
      "settings": {
         "index": {
            "creation_date": "1461757315198",
            "analysis": {
               "filter": {
                  "nGram_filter": {
                     "token_chars": [
                        "letter",
                        "digit",
                        "punctuation",
                        "symbol"
                     ],
                     "min_gram": "2",
                     "type": "nGram",
                     "max_gram": "20"
                  }
               },
               "analyzer": {
                  "nGram_analyzer": {
                     "filter": [
                        "lowercase",
                        "asciifolding",
                        "nGram_filter"
                     ],
                     "type": "custom",
                     "tokenizer": "whitespace"
                  },
                  "whitespace_analyzer": {
                     "filter": [
                        "lowercase",
                        "asciifolding"
                     ],
                     "type": "custom",
                     "tokenizer": "whitespace"
                  }
               }
            },
            "number_of_shards": "1",
            "number_of_replicas": "1",
            "uuid": "HngScPJJQcedP2l2PnFeNw",
            "version": {
               "created": "2030199"
            }
         }
      }
   }
}

Thanks in advance.

I'm sorry, but I have no idea what you're asking or what problem you'd like help diagnosing.

I am facing issue with elasticstack.

python manage.py show_mapping

{
   "core": {
      "mappings": {
         "modelresult": {
            "properties": {
               "django_ct": {
                  "type": "string"
               },
               "django_id": {
                  "type": "string"
               },
               "id": {
                  "type": "string"
               },
               "text": {
                  "type": "string"
                  "analyzer" : "custom_analyzer"
                  "search_analyzer" : "custom_search_analyzer"
               },
               "university": {
                  "type": "string"
                  "analyzer" : "custom_analyzer"
                  "search_analyzer" : "custom_search_analyzer"

               }
            }
         }
      }
   }
}

When I rebuild_index and try to access elastic search mapping using GET /index/_mapping

it gives the following mapping json

{
   "core": {
      "mappings": {
         "modelresult": {
            "properties": {
               "django_ct": {
                  "type": "string"
               },
               "django_id": {
                  "type": "string"
               },
               "id": {
                  "type": "string"
               },
               "text": {
                  "type": "string"
               },
               "university": {
                  "type": "string"
               }
            }
         }
      }
   }
}

I don't know why there is no analyzer field although I have followed every step.

When I debug and try to get the mapping value in backends.py it has analyzer and search_analyzer field but when I try to get the index mapping value from elasticsearch, it gives me above mapping.
thanks in advance.

The code does not work for indexing as it returns 400 because _boost has been deprecated from elasticsearch but haystack 2.4.1 build had _boost variable in elasticsearch_backend.py on line 138.

Solved the issue.
