ElasticSearch 5: MapperParserException with multi_field

elasticsearch, java, mapping

Solution

`multi-field` was deprecated in ES 1.x and completely removed in ES 5.x.

Now multi fields are supported via the use of `fields` which you can specify like this:

{  
  "type1":{  
    "properties":{  
        "name":{  
            "type":"text",
            "analyzer":"standard",
            "index":"analyzed",
            "store":"no",
            "search_analyzer":"standard"
            "fields": {
                "autocomplete":{  
                    "type":"text",
                    "analyzer":"autocomplete",
                    "index":"analyzed",
                    "store":"no",
                    "search_analyzer":"standard"
                }
            }
        }
    }
  }
}

Problem

This mapping hast worked with ES 2.X, now with ES 5 I get an exception: ``` { "type1":{ "properties":{ "name":{ "type":"multi_field", "fields":{ "name":{ "type":"string", "index_analyzer":"standard", "index":"analyzed", "store":"no", "search_analyzer":"standard" }, "name_autocomplete":{ "type":"string", "index_analyzer":"autocomplete", "index":"analyzed", "store":"no", "search_analyzer":"standard" } } } } } ``` } The exception is: No handler for type [multi_field] declared on field [name] Someone an idea? Thanks! ;)
