Elasticsearch Delete Mapping Property

Question

I am trying to figure out an approach to delete all entries for a specific property in an elasticsearch index and remove all type mappings for that property.

I have been looking at the following two doc pages: put mapping and delete mapping

From second link:

"Allow to delete a mapping (type) along with its data. The REST endpoint is /{index}/{type} with DELETE method."

What I think I need is a /{index}/{type}/{property}?

Do I need to recreate the whole index to accomplish this, i.e. moving and manipulating data between types?

For Example, calling GET on the mapping:

curl -XGET 'http://.../some_index/some_type/_mapping' 

result:

{   "some_type": {     "properties": {       "propVal1": {         "type": "double",         "index": "analyzed"       },       "propVal2": {         "type": "string",         "analyzer": "keyword"       },       "propVal3": {         "type": "string",         "analyzer": "keyword"       }     }   } } 

after this delete operation on propVal3 would return:

curl -XGET 'http://.../some_index/some_type/_mapping' 

result:

{   "some_type": {     "properties": {       "propVal1": {         "type": "double",         "index": "analyzed"       },       "propVal2": {         "type": "string",         "analyzer": "keyword"       }     }   } } 

and all data for propVal3 would be removed through the index.

You can not do that. Just forget that this value exists... ;-) If you really need to remove it, you will have to reindex your documents.
