Output field in autocomplete suggestion

Question

when I want to index a document in elasticsearch this problem occurring:

message [MapperParsingException[failed to parse]; nested: IllegalArgumentException[unknown field name [output], must be one of [input, weight, contexts]];]

I know that the output field removed from elasticsearch in version 5 but why? and what I have to do for getting single result for inputs?

Answer 1

output field removed from ElasticSearch in version 5, now _source filed returns with the suggestion. Example shown in below.

            },
            "suggest": {
                "type": "completion",
                "analyzer": "simple",
                "search_analyzer": "simple"
            }
        }
    }
