Hello.  
I have my index mapping with nested:

{  
"index\_test": {  
"mappings": {  
"search\_type": {  
"properties": {  
"person": {  
"properties": {  
"relation": {  
"properties": {  
"subject": {  
"type": "nested",  
"properties": {  
"firstName": {  
"type": "keyword",  
"fields": {  
"english": {  
"type": "text",  
"analyzer": "english"  
} } },  
"lastName": {  
"type": "keyword",  
"fields": {  
"english": {  
"type": "text",  
"analyzer": "english"  
} } } } } } } } } }} } }

But I want to add new field 'organization' to my nested 'subject'. How should I do it?

I am using Java API:  
/\*  
xContentBuilder.string = {  
"search\_type": {  
"properties": {  
"person.relation.subject.organization": {  
"type": "keyword",  
"fields": {  
"english": {  
"type": "text",  
"analyzer": "english"  
} } } } } }  
\*/  
m\_transportClient.admin().indices()  
.preparePutMapping( "index\_test")  
.setType( "search\_type" )  
.setSource( xContentBuilder ).get();

gives me EXCEPTION: object mapping [person.relation.subject] can't be changed from nested to non-nested

How to add new field for mapping of nested object?
