I'm using the following index template (derived from the Logstash index  
template):

```
{
  "template": "logstash-*",
  ...
  "mappings": {
    "_default_": {
      ...
      "dynamic_templates": [
        {
          "string_fields": {
            "match": "*",
            "match_mapping_type": "string",
            "mapping": {
              "type": "string",
              "index": "analyzed",
              "omit_norms": true,
              "fields": {
                "raw": {
                  "type": "string",
                  "index": "not_analyzed",
                  "ignore_above": 256
                }
              }
            }
          }
        }
      ]
    },
    "gerrit_event": {
      "dynamic_templates": [
        {
          "string_fields": {
            "match": "*",
            "match_mapping_type": "string",
            "mapping": {
              "type": "string",
              "index": "not_analyzed",
              "omit_norms": true,
              "fields": {}
            }
          }
        }
      ]
    }
  }
  ...
}

```

I thought this would've effectively deleted the .raw subfield for  
gerrit\_event documents, but that doesn't happen:

$ curl --silent -XGET '[http://localhost:9200/logstash-2015.04.25/\_mapping/gerrit\_event?pretty](http://localhost:9200/logstash-2015.04.25/_mapping/gerrit_event?pretty)' | head -n 22  
{  
"logstash-2015.04.25" : {  
"mappings" : {  
"gerrit\_event" : {  
"dynamic\_templates" : [ {  
"string\_fields" : {  
"mapping" : {  
"index" : "not\_analyzed",  
"type" : "string",  
"fields" : {  
"raw" : {  
"index" : "not\_analyzed",  
"ignore\_above" : 256,  
"type" : "string"  
}  
},  
"omit\_norms" : true  
},  
"match" : "\*",  
"match\_mapping\_type" : "string"  
}  
} ],

Is this expected? If so, why, and is there another way to remove  
accomplish what I want, i.e. have a .raw subfield for dynamically mapped  
string fields in all types but not gerrit\_event? (Without removing the  
subfield from _default_ and adding it in many other places, obviously.)
