# Manage page relations
Documents are associated to pages via "document sets". You can retrieve document sets for a page, then retrieve
documents that belong to those sets. You can still retrieve all documents for a page if you want to.
## Get document sets for a page
```php
$dms = DMS::inst();
$sets = $dms->getDocumentSetsByPage($myPage);
```
You can also request sets directly from the SiteTree instance:
```php
$sets = $page->getDocumentSets();
```
## Get all related documents for a page
`DMS::getByPage` will exclude currently embargoed documents by default. To include embargoed documents as well
add `true` as the second argument.
```php
$dms = DMS::inst();
$documents = $dms->getByPage($myPage);
$documentsIncludingEmbargoed = $dms->getByPage($myPage, true);
```
You can also request this directly from the SiteTree instance:
```php
$documents = $myPage->getAllDocuments();
```
