Retrieve the type Mapping

We now have a single index called 'Suburbs' with a single document loaded into it. Elasticsearch has created a mapping for our suburb type based upon the first document we've loaded in.

To retrieve the mapping:

curl -s -XGET "http://127.0.0.1:9200/suburbs/suburb/_mapping?pretty=true" > mapping.json


You will now have a file called mapping.json which contains the mapping for the suburbs index and suburb type. Open the mapping.json file. Elasticsearch includes the index in the mapping:

{
"suburbs" : {
"mappings" : {...
}
}
}


The PUT mapping option on the Elasticsearch API allows you to define a mapping for a specifc type, therefore we need to remove the index definition from the mapping.json file - so remove the above section leaving the suburb type only:

{
"suburb": {.....
}
}


You'll notice that Elasticsearch by default has defined the geometry field on the suburb as including a coordinates and type property.

"geometry" : {
"properties" : {
"coordinates" : {
"type" : "double"
},
"type" : {
"type" : "string"
}
}
}


We need to update the mapping to tell Elasticsearch that the geometry field is actually a geo shape type. Update the file as follows:

"geometry" : {
"type": "geo_shape"
}
