Strange behavior: same id in different types

Elastic Stack Elasticsearch
1

Hi ! I just started play with ES and noted some strange behavior:

First I just indexed 2 documents:
curl -XPUT http://192.168.0.118:9200/test/company/apple -d '{data:"Apple
corp"}'
curl -XPUT http://192.168.0.118:9200/test/fruit/apple -d '{data:"Just red
apple"}'

As you can see, they have same id and placed in same index,but different
types.
Ok, next I perform multi get request:

curl -XGET http://192.168.0.118:9200/test/_mget?pretty -d '{ids:["apple"]}'

Response:

{
"docs" : [ {
"_index" : "test",
"_type" : "fruit",
"_id" : "apple",
"_version" : 1,
"found" : true, "_source" : {data:"Just red apple"}
} ]
}

As you can see only one document returned. Why not both? I find such
behavior very ambiguous. I think if we request whole index, so all
documents with given id should be returned regardless of type.

Hey,

your request is already ambigous. You specify a single ID, but expect two
results to return, as you did not specify a type. However to identify a
document in a unique fashion, you need the tuple of index/type/id, of which
a type is missing here.

So, either specify all three, or maybe elasticsearch should possibly reject
such a request and return an error message. Maybe create a github issue?
