Hello,
We're trying to send raw string document to `_bulk` endpoint for bulk
indexing and this will save us json serialization/deserialization time.
But unfortunately in our document generation step, the custom `_id` field
is generated inside the document string. And this seems to break the bulk
endpoint.
```
{ "create" : { "_index" : "test", "_type" : "urls"} }
{ "url" : "abcde", "_id": 15 } # our document structure
```
This does not works.
```
{ "create" : { "_index" : "test", "_type" : "urls", "_id": 15} }
{ "url" : "abcde"}
```
This works well.
Is there anyway we can send documents with `_id` fields inside?
Thanks.
