I would like to add a JSON file with a lot of lines like this.

```
{"index":{"_index": "fake", "_type": "keyword", "_id":"2"}}
{"info":"2", "bob":3}

```

Is there a way of defining the type and index once and for all for a JSON file (because it will be the same thing for each line)

I was wondering also what the different types were?

I know integer and keyword. Is there a type for "indentation"?

Like if I would have my JSON file like this:

`"_id":{"$oid":"52287a4ee4b07193f703c23f"}}`

Like I mentioned in my [previous answer](https://discuss.elastic.co/t/validation-failed-because-of-missing-type-with-bulk-api/118465/6), you can remove the index and type information from your JSON file like this:

```
{"index":{"_id":"2"}}
{"info":"2", "bob":3}

```

and then add those to your curl command

```
curl -XPOST -H 'Content-Type: application/json' localhost:9200/fake/type/_bulk --data-binary @/path/to/your/file.json

```

Also note that the type information has nothing to do with your field types (keyword, integer, etc), but it is a [mapping type](https://www.elastic.co/guide/en/elasticsearch/reference/current/indices-put-mapping.html), i.e. the place where you define all your index fields

Finally, the `_id` can only take literal value, but not an object value. You could hash `{"$oid":"52287a4ee4b07193f703c23f"}` into some string and use that string as ID, though

Sorry I didn't pay attention and didn't see the "type" in your curl.
