Defining mapping within elasticsearch with json file

Question

I'm trying to use a json file to define the default mapping for each index. This is what I am trying to do:

/usr/share/elasticsearch/config/default-mapping.json

{
    "item": {
        "properties": {
            "uuid": {"type": "string", "store": "yes", "index": "no"},
            "title": {"type": "string", "store": "yes", "boost": 5,
                      "index": "analyzed", "analyzer": "english"},
            "description": {"type": "string", "store": "yes", "boost": 3,
                            "index": "analyzed", "analyzer": "english"},
}

When I try and query my index_test elasticsearch index I get this:

curl -XGET 'http://...:9200/index_test/_mapping'
{"index_test":{"mappings":{}}}

I used the documentation found on here.

You can create index template with default configuration(index settings, mapping etc) for your indices.

To do this, change content of default-mapping.json file to something like:

{
    "template_1" : {
        "template" : "*",
        "mappings" : {
            "type" : {
                "properties" : {
                    "uuid" : {
                        "type" : "string",
                        "store" : "yes",
                        "index" : "no"
                    },
                    "title" : {
                        "type" : "string",
                        "store" : "yes",
                        "boost" : 5,
                        "index" : "analyzed",
                        "analyzer" : "english"
                    },
                    "description" : {
                        "type" : "string",
                        "store" : "yes",
                        "boost" : 3,
                        "index" : "analyzed",
                        "analyzer" : "english"
                    }
                }
            }
        }
    }
}

Move default-mapping.json file to /usr/share/elasticsearch/config/templates directory
Create a new index
```
POST /newindex
```

Mapping of newly created index:

{
    "newindex" : {
        "mappings" : {
            "type" : {
                "properties" : {
                    "description" : {
                        "type" : "string",
                        "boost" : 3,
                        "store" : true,
                        "analyzer" : "english"
                    },
                    "title" : {
                        "type" : "string",
                        "boost" : 5,
                        "store" : true,
                        "analyzer" : "english"
                    },
                    "uuid" : {
                        "type" : "string",
                        "index" : "no",
                        "store" : true
                    }
                }
            }
        }
    }
}

Hope this helps you.

assuming you have create the index index_test already, you need to execute the following (as in your link):

$ curl -XPUT 'http://localhost:9200/index_test/my_type/_mapping' -d '
{
  "my_type": {
    "properties": {
      "uuid": {
        "type": "string",
        "store": "yes",
        "index": "no"
      },
      "title": {
        "type": "string",
        "store": "yes",
        "boost": 5,
        "index": "analyzed",
        "analyzer": "english"
      },
      "description": {
        "type": "string",
        "store": "yes",
        "boost": 3,
        "index": "analyzed",
        "analyzer": "english"
      }
    }
  }
}

'

The important bit is to note that the field in the payload corresponds to the type-name (generically I took my_type).

Verify with a GET on url:9200/index_test/_mapping/my_type?pretty.

Really good answer. I would like to add one thing. You might not find templates directory into elasticsearch/config. You should create one and put your mapping file into it.

your JSON document is not valid. it should be :

{
    "my_type": {
        "properties": {
            "uuid": {
                "type": "string",
                "store": "yes",
                "index": "no"
            },
            "title": {
                "type": "string",
                "store": "yes",
                "boost": 5,
                "index": "analyzed",
                "analyzer": "english"
            },
            "description": {
                "type": "string",
                "store": "yes",
                "boost": 3,
                "index": "analyzed",
                "analyzer": "english"
            }
        }
    }
}

i advise you to always check your JSON documents when you modify your mapping. ElasticSearch will just ignore your mapping and not prompt you any error when you send a non valid JSON document as mapping
