Answer 1

The error is quite clear if you ask me, you need to specify analyzer for _all in your movie mapping. Setting index_analyzer was removed in Elasticsearch 2.0.

        "_all": {
            "analyzer": "nGram_analyzer",
            "search_analyzer": "whitespace_analyzer"
        },

Anywise

then what is index_analyzer ? can you please tell me – Nealneala

In Elasticsearch before 2.0 you could set index_analyzer, search_analyzer or simply analyzer. The last one was a shorthand for setting both index_analyzer and search_analyzer to the same value. In Elasticsearch 2.0 they changed it so that index_analyzer is now just analyzer and if you don't set a separate search_analyzer the value from analyzer is used for that as well. – Eddieeddina
