I am trying to add copy\_to for the existing index. For Ex: PUT /my\_index { "mappings":{ "my\_type":{ "properties":{ "user\_name":{ "type":"string", "copy\_to":["key"], "index":"not\_analyzed", "include\_in\_all":false } } }, "key":{ "type":"string", "store":"yes" } } } I have the data already in the user\_name. When updating the mapping will these data gets copied to the copy\_to field ? When i index new set of inputs will the new inputs only gets copied to the copy\_to (key) field ? Or do we need to do re-index to get the changes reflected ? How to update copy to without re-indexing the whole document or can we update only the specific user\_name document to get the changes reflected ? ---

If you have indexed: ```auto PUT my_index/my_type/1 { "user_name": "bar" } ``` Then send again: ```auto PUT my_index/my_type/1 { "user_name": "bar" } ``` Your document `1` will have its field copied to `key` field. ---

you mean we need to re index that specific document where we are using copy\_to without re indexing we cannot update the copy\_to field? ---
