Search Nested documents

Elastic Stack Elasticsearch

Hi All,
I saw lot of messages in the group about "parent/child" and "nested",
but am still unable to solve my issue.

I am holding nested type as shown here:
http://www.elasticsearch.org/guide/reference/query-dsl/nested-query.html
The main reason for this is to make some facets on the nested type
"type1.obj1".

Some times though I need to query only the nested type "type1.obj1"
and to extract it's _source. I tried with:
#curl -XGET http://localhost:9200/giftsplusindex/type1.obj/_search
but it didn't work.

Then I tried with the query bellow, but it still returns the type1
documents with all the type1.obj1 documents inside and not only obj1
documents:
#curl -XGET http://localhost:9200/giftsplusindex/type1/_search?pretty=true
-d '
{
"query": {
"nested": {
"path": "obj1",
"query": {
"match_all" : { }
}
}
},
"size": 10,
"from": 0
}'

I suppose this will work with "parent/child" but in this case I can
not make facets on the child I think?

I guess I am doing some design error.

You want to get just the nested document source? If so, you can't, you get back the full document you indexed back.
