Hi,

Is it possible to define field mapping under a dynamic object for every  
field? I don't know in advance the name of the fields, but all should have  
been treated as string keywords. Imagine something similar for the mapping:

myCustomMapping {  
"fieldA": { "type": "string", "index": "analyzed", "analyzer": "keyword",  
"store":"yes" }  
"fieldB": { "type": "string", "index": "analyzed", "analyzer": "keyword",  
"store":"yes" }  
"fieldC": { "type": "string", "index": "analyzed", "analyzer": "keyword",  
"store":"yes" }  
"customFields": {  
"type": "object",  
"dynamic": "true",

- 

```
   "_defaultMapping" : {
          { "type": "string", "index": "analyzed", "analyzer": 

```

"keyword", "store":"yes" }  
}

- }  
}

I'm not sure, that my intentions are clear enough, I would like to search  
by any of the customFields as terms.  
Any suggestions how to achieve this, are welcomed.

Thanks  
Zsombor

You can do that using dynamic templates in the root object mapper.
