# Collections

A [`Collection`](#tag/Collections) is a user defined set of [`Asset`](#tag/Assets) resources.

The [`Asset`](#tag/Assets) resources in a [`Collection`](#tag/Collections) are not returned with the [`Collection`](#tag/Collections) resource.
To get the [`Asset`](#tag/Assets) resources you must create an [Asset Search](#operation/postAssetSearch) and use the [`Collection.id`](#tag/Collections) as the value in a `COLLECTIONS` : `FIELD_EQUALS` criterion.

Searching allows you to find [`Collection`](#tag/Collections) resources in your Dash matching specific criteria.

A list of sorts can also be provided to control the order in the which the results are returned.
