curl -s -X POST 'http://localhost:9200/fields_test/_refresh'

# Response doesn't contain person field. Message is returned ok (and its not stored and not analyzed)
curl -s "http://localhost:9200/fields_test/_search?pretty=1" -d '{
  "fields" : ["message", "person"],
  "query": { "query_string" : { "query" : "Shay"} }
}'


# When requesting _source.person, then its returned ok. Seems fields param has problem with type: object
curl -s "http://localhost:9200/fields_test/_search?pretty=1" -d '{
  "fields" : ["message", "_source.person"],
  "query":{ "query_string" : { "query" : "Shay"} }
}'

The same behaviour might be observed with arrays. Having a mapping like this:

{
  "gallery": {
    "properties": {
      "title": {
        "type": "string"
      },
      "images": {
        "dynamic": "true",
        "properties": {
          "title": {
            "type": "string"
          }
        }
      }
    }
  }
}

querying for images won't return any images. Replacing it with _source.images will work, though. I still, however, can't figure out how to query for single fields, e.g. images.title (_source.images.title doesn't work).

Hello @mchruszcz. Please can you gist whole your test suite (with whole mapping, document creating and searching)? Its hard for me to recreate behaviour which you described.

@vhyza, I described it in https://gist.github.com/1300910.

@mchruszcz thanks. I'm not sure if I understand it correctly. According this discussion karmi/retire#31 you have to add _source prefix before compound fields. I don't know if its possible to request one field of object type.

@kimchy, please, is somehow possible to have only one object field in fields response (as described in https://gist.github.com/1300910)?
