I'm having issues getting the "copy\_to" functionality to work. It seems pretty straight forward, so I wasn't expecting any problems. Here is my index creation call: curl -XPUT [http://esnode:9200/test\_index](http://esnode:9200/test_index) -d '{ "settings" : { "number\_of\_shards" : 1, "number\_of\_replicas" : 1, "index.mapping.ignore\_malformed" : true }, "mappings" : { "default" : { "properties": { "name" : { "type" : "string", "copy\_to" : "name\_phonetic" }, "name\_phonetic" : { "type" : "string" } } } } }' curl -XPUT [http://esnode:9200/test\_index/default/1](http://esnode:9200/test_index/default/1) -d '{ "name" : "smith" }' When I query against test\_index/default, I can see that "smith" is in the "name" field. However the "name\_phonetic" field is blank. What am I missing? Thank you! -- Michael -- You received this message because you are subscribed to the Google Groups "elasticsearch" group.

Nothing. Elasticsearch does not modify \_source field which contains the document you sent. It does create in the inverted index a new field.

I want to expand on this a bit - both copy\_to and transform only modify the _indexed_ document, not the source document. The thinking is that you can modify the source document yourself in the source application but the source application _can't_ modify the indexed document without modifying the source document. Copy\_to is useful for playing tricks like concatenating multiple fields together so you only have to search on one of them at a time rather than all of them. For what it looks like you are doing I suggest using nested fields: > **[Multi-fields | Elasticsearch Guide \[1.3\] | Elastic](https://www.elastic.co/guide/en/elasticsearch/reference/1.3/_multi_fields.html)** Nik On Mon, Apr 13, 2015 at 11:23 AM, David Pilato [david@pilato.fr](mailto:david@pilato.fr) wrote: > Nothing. > > Elasticsearch does not modify \_source field which contains the document > you sent. > It does create in the inverted index a new field.

Nikolas, Thank you for the response. This is definitely helpful and answers my question. Nested fields looks to solve what I'm trying to do for this particular use case; using nest fields for name variations will work perfectly. For other use cases, such as creating a title to the record/document based on 2 or more fields, that doesn't work. The copy\_to and transform functionality will allow me to make a "title" field searchable, but not necessarily viewable. It looks like I'll be forced to do that outside of Elasticsearch. This was something I was easily able to do with Solr, so I anticipated a similar capability. ## Thanks again!

Yes _but_ its generally better to do those transforms on the source application. The idea is that you'll often want to return multiple things from the source so loading the whole thing is usually better than loading a bunch of stored fields. If your looking for the minimal possible amount of work to port from solr to elasticsearch then go ahead but if you are looking to do whats more normal for Elasticsearch applications then transform in the source application.
