# Creating a document to index with stream field data

![Elasticsearch REST Bulk Insert step, Document tab - Create index option](/files/MNmWvBQU5yzdC2J6mD9G)

Use the **Create a document to index with stream field data** option if you want to turn each row of stream data into a unique JSON document to be indexed in the bulk request. You must define the fields to use from the input stream with a target name. Click **Get Fields** to automatically find all incoming stream data.

| Field           | Description                                                                                               |
| --------------- | --------------------------------------------------------------------------------------------------------- |
| **Name**        | Enter the name of the source field that the step receives on the input stream.                            |
| **Target name** | Enter the name of the destination field in the generated JSON document to use for the input stream field. |

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://docs.pentaho.com/pdia-data-integration/9.3-data-integration/pdi-transformation-steps-reference-overview/elasticsearch-rest-bulk-insert/options-elasticsearch-rest-bulk-insert/document-tab-elasticsearch-rest-bulk-insert/creating-a-document-to-index-with-stream-field-data-elasticsearch-rest-bulk-insert.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
