# Use the Advanced Object Picker

> Learn about the Advanced Object Picker window for references.

The **Advanced Object Picker** window is similar to the [**Search** window](/engine/6000.0/manual/unity-editor/editor-navigating-managing/editor-searching/search-overview.md) in the following ways:

* It supports visual queries.
* It lists results in four tabs: All, Project, Resources, and Hierarchy. To learn more, refer to [Search Providers](/engine/6000.0/manual/unity-editor/editor-navigating-managing/editor-searching/search-overview/search-filter-by-provider.md).
* It has three views: grid, list, and table.
* It can display an Editor panel for an item, which allows you to edit the object's properties before selecting it as a reference.

## Use the Advanced Object Picker in all reference fields

To use the **Advanced Object Picker** in all reference fields in the Unity Editor:

1. From the main menu, go to **Edit** > **Preferences** (macOS: **Unity** > **Settings**).

2. In the **Preferences** window, go to the **Search** tab.

3. Under **Search Engines**, from the **Object Selector** dropdown, select **Advanced**.

   To revert to the default object selector, select **Classic** from the dropdown.

4. Close the **Preferences** window.

## Assign the Advanced Object Picker to individual property

To add the `SearchContextAttribute` to specific object properties, refer to [SearchContextAttribute](/engine/6000.0/script-reference/unityengine/search/searchcontextattribute.md).
