The Index Manager

The Index Manager allows you to create, edit, and remove search indexes. Indexes update when you add or change content in your project.

Index types

• Asset - An index of all Assets in a Project. This index is created automatically when you create a Project and rebuilds when you add or modify new content. The Asset index includes all Assets including Prefabs and scenes, but it doesn’t index the content of a sceneA Scene contains the environments and menus of your game. Think of each unique Scene file as a unique level. In each Scene, you place your environments, obstacles, and decorations, essentially designing and building your game in pieces. More info
  See in Glossary or a nested hierarchy in a PrefabAn asset type that allows you to store a GameObject complete with components and properties. The prefab acts as a template from which you can create new object instances in the scene. More info
  See in Glossary.
• Package - An index containing Assets in the Packages.
• Prefab - An index containing only the GameObjectsThe fundamental object in Unity scenes, which can represent characters, props, scenery, cameras, waypoints, and more. A GameObject’s functionality is defined by the Components attached to it. More info
  See in Glossary which are part of Prefabs.
• Scene - An index of Assets in any scene
• User - An index that is created for you and is not shared with the project.

By default Unity creates the Asset index. To use Prefab, Package, Scene, and User indexes, you must create them in the Index Manager.

To open the Index Manager choose Windows > Search > Index Manager.

Index results

The following tabs contain information about the index:

• Assets: Displays the files indexed.
• Objects: (Prefab and Scene indexes only) Displays the object identifiers.
• Keywords: Displays the available searchable Properties or filters you can use to further narrow your search results.

Index sizes

To determine the index options you need, refer to this table.

Note: The more options you add to the index, the longer it will take to generate your first index.

Add an index

1. Open the Index Manager.
2. Click the plus (+) sign in the left pane of the Index Manager window and select the type of index you want to create.
3. Customize your index settings in the right pane and click Create.
4. Name your index in the Save Index Settings window and click Save.
   Your index builds automatically. Depending on the size of the project and your index settings, this may take some time.

Edit an index
