Hi,

I would like to delete a field from a mapping.  
As I've read I can do this with reindexing the whole documents but currently however I create the new index without the removed field the reindexed documents contains that field.  
How can I reindex the documents without containing the old field?

I use the following script at reindexing:

> ctx.\_source.remove('text')

New Mapping looks like this:

> {  
> "mapping": {  
> "properties": {  
> "id": {  
> "type": "text",  
> "fields": {  
> "keyword": {  
> "type": "keyword",  
> "ignore\_above": 256  
> }  
> }  
> },  
> "num1": {  
> "type": "long"  
> },  
> "parentfolderid": {  
> "type": "text",  
> "fields": {  
> "keyword": {  
> "type": "keyword",  
> "ignore\_above": 256  
> }  
> }  
> },  
> "relation": {  
> "type": "join",  
> "eager\_global\_ordinals": true,  
> "relations": {  
> "root": "field"  
> }  
> },  
> "string1": {  
> "type": "text",  
> "fields": {  
> "keyword": {  
> "type": "keyword",  
> "ignore\_above": 256  
> }  
> }  
> }  
> }  
> }  
> }

I receive a response like this when I query the new documents:

> {  
> "took" : 0,  
> "timed\_out" : false,  
> "\_shards" : {  
> "total" : 1,
