copy_to of metadata field isn't working (v3.0.2)

[gpaul]

The following set of steps against a fresh elasticsearch 2.0.0 instance with v3.0.2 of this plugin installed shows that copy_to isn't working for the name field. I doubt it is working for the other metadata fields, either.

You can copy/paste this in your shell.

# create a mapping
curl -XPOST 'http://localhost:9200/test_copyto' -d '{
  "mappings": {
    "person": {
      "properties": {
        "copy_dst": { "type": "string" },
        "doc": {
      "type": "attachment",
      "fields": {
        "name": { "copy_to": "copy_dst" }
          }
    }
      }
    }
  }
}'
## => {"acknowledged":true}

Ping. Should I open this issue against the main elasticsearch repository now that this plugin is moving there?

[dadoonet]

Did you try the same script with elasticsearch 1.7? I'd like to know if it's a regression or if it has always been there.

I know that copy_to feature is supposed to work for the extracted text but I don't think it worked for metadata.

If I'm right (so it's not an issue but more a feature request), then you can open it in elasticsearch repo.
If I'm wrong (so it's a regression), then keep it here.

[gpaul]

It seems like a regression:
elasticsearch 1.7.0 with mapper-attachments 2.7.1
yields

curl -XPOST 'http://localhost:9200/test_copyto/person/_search' -d '
 {
   "query": {
     "query_string": {
       "default_field": "copy_dst",
       "fields": ["copy_dst"],
       "query": "my-test.doc"
     }
   }
 }
 '
#{"took":3,"timed_out":false,"_shards":{"total":5,"successful":5,"failed":0},"hits":{"total":1,"max_score":0.02250402,"hits":[{"_index":"test_copyto","_type":"person","_id":"1","_score":0.02250402,"_source":{
#  "doc": {
#    "_content": "e1xydGYxXGFuc2kNCkxvcmVtIGlwc3VtIGRvbG9yIHNpdCBhbWV0DQpccGFyIH0=",
#    "_name": "my-test.doc"
#  }
#}}]}}

Thank you @gpaul

It's also not working with the .content field
