# Index Documents

The **Document Index** is the ordered, structured list of your documents that becomes the spine of your court bundle (it's a different thing from the search index used to find documents). BriefTech builds it automatically from the documents in your matter, assigning serial numbers by order. The guides below help you refine that index — reorder documents, add headings, split into volumes, and more.

* [Reorder documents and add structure](/how-to-guides/index/reorder-documents-add-structure.md) — Drag documents into the order you want and add headings.
* [Manage headings in the Document Index](/how-to-guides/index/manage-index-headings.md) — Add, rename, move, sort, indent, and delete the headings that group your documents.
* [Add or edit sub-index entries](/how-to-guides/index/add-edit-sub-index-entries.md) — Add, edit, or remove the sub-index entries that appear beneath a document in the index.
* [Sort documents in the Document Index](/how-to-guides/index/sort-documents-in-index.md) — Sort the Document Index by date, file name, or description.
* [Split a bundle into volumes](/how-to-guides/index/split-into-volumes.md) — Control how the bundle is split into volumes — BriefTech splits automatically by page count, and you can split by heading or force a break.

To set the columns and bundle settings (hyperlinks, sort order, volume options) from the toolbar menu, see the [Document Index presets](/reference/index-presets.md) reference. Presets don't set serial numbers.

**New to this?** For a guided, end-to-end walkthrough — from uploading documents to a finished, exported package — follow [Prepare a List of Documents for Disclosure](/get-started/prepare-disclosure-list.md).

**Next step:** with your Document Index built, [build the court bundle](/how-to-guides/bundle.md) from it.

## 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://help.brieftech.ai/how-to-guides/index.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.
