Strange behavior: results count depend on arguments count

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"}'

According to example above we have test index with 2 documents (both with
"apple" id) in different types.
When we make curl -XGET http://192.168.0.118:9200/test/_mget?pretty -d
'{ids:["apple","apple"]}'
We see this:
{
"docs" : [ {
"_index" : "test",
"_type" : "fruit",
"_id" : "apple",
"_version" : 1,
"found" : true, "_source" : {data:"Just red apple"}
}, {
"_index" : "test",
"_type" : "fruit",
"_id" : "apple",
"_version" : 1,
"found" : true, "_source" : {data:"Just red apple"}
} ]
}

As you can see documents are duplicated.
So if we request curl -XGET http://192.168.0.118:9200/test/_mget?pretty -d
'{ids:["apple","apple","apple"]}' we will see 3 documents in result set and
so on.

I think the right way to resolve this issue is to ignore duplicate
identificators in "ids" parameter.

So, what is happening here.

1st request:
You set index to test
type is not set
id is apple
It "guess" the type and send you the document from fruit type.

2nd request:
It's exactly the same request as the first one. So it gives you the same response.

To have the correct results, you should ask for:

GET /test/_mget?pretty
{
"docs" : [
{
"_type" : "company",
"_id" : "apple"
},
{
"_type" : "fruit",
"_id" : "apple"
}
]
}

Or you should use unique ids for the whole index.
