First I just indexed 2 documents:
curl -XPUT [http://192.168.0.118:9200/test/company/apple](http://192.168.0.118:9200/test/company/apple) -d '{data:"Apple
corp"}'
curl -XPUT [http://192.168.0.118:9200/test/fruit/apple](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](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](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.
