Here is the json:  
{ "id": "100004",  
"description": "some description",  
"brand": "brand",  
"displayName": "product",  
"customProperties": {  
"property1": "value1",  
"property2": "value2" ....  
}  
}  
child elements of "customProperties" could be added any time, and we can't  
know the names.  
So,I want to facet all of them one time.  
Is there any solutions? I can't find anything about that, can Elasticsearch  
support that right now?  
Thanks!!!

When a new field is added to the document type, the mapping is  
automatically updated by default. You can get the mapping and facet on  
whichever fields you want.

Cheers,
