# Label Filtering

The *Explorer* view in Index lets you view and filter data units by labels across all your Encord projects, and add matching data units to Collections for further curation.

## Filter

You can filter data units in Index based on the presence of labels, and the source of those labels (Projects and branches).

</div>

The following filters are available:

| Filter             | Description                                                           |
| ------------------ | --------------------------------------------------------------------- |
| **Label Class**    | Filter data units that contain labels from a specific ontology class. |
| **Label Projects** | Filter data units that contain labels from specific Projects.         |
| **Label Branches** | Filter data units that contain labels from specific label branches.   |

## Select Labels to Display

You can display labels directly on data units in the Data, Frames, and Video views. These settings control **which labels are shown**, but do not affect which data units are included in your filtered results.

The sidebar allows you to control which labels are displayed on each data unit.
