Elasticsearch : Root mapping definition has unsupported parameters index : not_analyzed

Question

Hi all I am trying to create schema Test.

PUT /test
{
    "mappings": {
        "field1": {
            "type": "integer"
        },
        "field2": {  
            "type": "integer"
        },
        "field3": {
            "type": "string",
            "index": "not_analyzed"
        },
        "field4": {
            "type": "string",
            "analyzer": "autocomplete",
            "search_analyzer": "standard"
        }
    },
    "settings": {
        bla
        bla
        bla
    }
}

I am getting the following error

{
    "error": {
        "root_cause": [{
            "type": "mapper_parsing_exception",
            "reason": "Root mapping definition has unsupported parameters: [index : not_analyzed] [type : string]"
        }],
        "type": "mapper_parsing_exception",
        "reason": "Failed to parse mapping [featured]: Root mapping definition has unsupported parameters:  [index : not_analyzed] [type : string]",
        "caused_by": {
            "type": "mapper_parsing_exception",
            "reason": "Root mapping definition has unsupported parameters:  [index : not_analyzed] [type : string]"
        }
    },
    "status": 400
}

Please help me to resolve this error

You're almost here, you're just missing a few things:

PUT /test
{
  "mappings": {
    "type_name": {                <--- add the type name
      "properties": {             <--- enclose all field definitions in "properties"
        "field1": {
          "type": "integer"
        },
        "field2": {
          "type": "integer"
        },
        "field3": {
          "type": "string",
          "index": "not_analyzed"
        },
        "field4,": {
          "type": "string",
          "analyzer": "autocomplete",
          "search_analyzer": "standard"
        }
      }
    }
  },
  "settings": {
     ...
  }
}

UPDATE

If your index already exists, you can also modify your mappings like this:

PUT test/_mapping/type_name
{
    "properties": {             <--- enclose all field definitions in "properties"
        "field1": {
          "type": "integer"
        },
        "field2": {
          "type": "integer"
        },
        "field3": {
          "type": "string",
          "index": "not_analyzed"
        },
        "field4,": {
          "type": "string",
          "analyzer": "autocomplete",
          "search_analyzer": "standard"
        }
    }
}

UPDATE:

As of ES 7, mapping types have been removed. You can read more details here
