Hello. I have different types of fields in my index type:

{  
"test\_index": {  
"mappings": {  
"search\_type": {  
"properties": {  
"keywords": {  
"type": "keyword"  
},  
"person": {  
"properties": {  
"relation": {  
"properties": {  
"subject": {  
"type": "nested",  
"properties": {  
"first": {  
"type": "keyword"  
}  
},  
"last": {  
"type": "keyword"  
}  
}  
}  
}  
}  
}  
}  
},  
"relation": {  
"properties": {  
"first": {  
"type": "keyword"  
}  
},  
"last": {  
"type": "keyword"  
}  
}  
}  
}  
}  
}  
}  
}  
}  
}

I want to remove fields and I am using reindex, it works fine with simple field like 'keywords':

ReindexAction.INSTANCE.newRequestBuilder( m\_transportClient )  
.source( "test\_index" )  
.destination( "test\_index\_new" )  
.script( new Script( "if (ctx.\_type=="search\_type") { ctx.\_source.remove("keywords") }" ) ).get();

But how should I build the script if I want to delete:

1. person.relation.subject.last (field from nested)
2. person.relation.subject (nested field)
3. relation.first (field from composite field)
4. relation (composite field with it's children)
