# Indexing

> Understand which parts of your help center are uploaded to Algolia and learn how to exclude parts from the search.

After installing Algolia for Zendesk,
your public help center articles will be synced with Algolia.
You can also trigger an update from the [Tasks list](https://dashboard.algolia.com/connectors/tasks) in the Algolia dashboard.

## What's indexed by Algolia

The Algolia connector automatically extracts the following Zendesk content:

* [Articles](https://developer.zendesk.com/api-reference/help_center/help-center-api/articles/)
* [Categories](https://developer.zendesk.com/api-reference/help_center/help-center-api/categories/)
* [Sections](https://developer.zendesk.com/api-reference/help_center/help-center-api/sections/)

Only publicly accessible articles are indexed.
Publicly accessible articles exclude articles in draft mode and articles that aren't visible to everyone.
Content from Zendesk community forums isn't included.

By default, whole articles are indexed, but you can exclude individual articles or parts of an article from your search.

  After your Zendesk articles are indexed,
  check the details of your indices
  in the [Algolia dashboard](https://dashboard.algolia.com/explorer).

## Exclude content

To **exclude complete articles** from your search,
edit the article in Zendesk,
and [add the `algolia-ignore` content tag](https://support.zendesk.com/hc/en-us/articles/5003635888410-Adding-content-tags-to-group-related-articles) to it.

To exclude **parts of an article**,
[edit the article's source code in Zendesk](https://support.zendesk.com/hc/en-us/articles/4408824584602-Editing-the-source-code-of-help-center-articles), and add these HTML comments before and after the content you want to exclude:

```html HTML icon=code-xml theme={"system"}
<!-- algolia-ignore -->
<p>This content won't appear in search results.</p>
<!-- /algolia-ignore -->

<p>This content will appear in search results.</p>
```

## Allow Algolia IP addresses

If you [restrict access to your Zendesk help center](https://support.zendesk.com/hc/en-us/articles/4408894156186-Restricting-access-to-Zendesk-Support-and-your-help-center-using-IP-restrictions),
you must allow these IP addresses so that Algolia can index your content:

* `104.196.103.173`
* `35.234.69.129`
