If there's anybody who can point me in the right direction, that would be greatly appreciated 🙂

I'm able to import a collection from MongoDB to elasticsearch, with the following transform\_file.js code:

```
t.Source("source", source, '/^categories$/').Save("sink", sink, "/.*/")

```

In elasticsearch (using [appbase.io](http://appbase.io)), the data is indexed with the MongoDB collection 'categories' being the only type, while all the MongoDB documents are elasticsearch documents:

However, I want each of the MongoDB documents to instead be their own elasticsearch type. So instead of 'categories' being the only type in elasticsearch, I want the types to be BMW and Audi. Ideally named category\_bmw and category\_audi.

I assume it's the code after '.Save' that has to be changed, but I'm not exactly sure what changes to make.

EDIT: I'm using elasticsearch version 5.

Note that [mapping types are being deprecated](https://www.elastic.co/guide/en/elasticsearch/reference/master/removal-of-types.html) and indices with more than one type can not be created in version 6.0 onwards. By relying on different types in your induces you are setting yourself up for a difficult upgrade path.

Thanks for letting me know. I assume I would just have to make some changes to the transform\_files.js when upgrading to v6. Any alternative way you would suggest I do this? Using mapping types seems to be the only way I can do this at the moment, because I'm using [appbase.io](http://appbase.io) with reactive search.
