# Scene

> Use this API to perform searches in the Scene. Engines for this type of search implement the ISceneSearchEngine interface.

## Definition

* **Type:** Class
* **Namespace:** [UnityEditor.SearchService](/engine/6000.3/script-reference/unityeditor/searchservice.md)
* **Assembly:** UnityEditor

> **Warning:**
>
> **Removed.** Scene has been deprecated. Use SceneSearch instead
>
> **Upgrade to** [SceneSearch](/engine/6000.3/script-reference/unityeditor/searchservice/scenesearch.md)

```csharp
public static class Scene
```

## Remarks

Registered Scene engines are called during searches in the Scene hierarchy. When the default object selector is used, they are also called for GameObject searches.

The following example creates a Scene engine:

```csharp
using System;
using System.Collections.Generic;
using System.Linq;
using UnityEditor;
using UnityEditor.SearchService;
using UnityEngine;
using Object = UnityEngine.Object;

[SceneSearchEngine]
class TestSceneFilterEngine : ISceneSearchEngine
{
    public string name => "My Custom Engine";

    public void BeginSession(ISearchContext context)
    {
    }

    public void EndSession(ISearchContext context)
    {
    }

    public void BeginSearch(ISearchContext context, string query)
    {
    }

    public void EndSearch(ISearchContext context)
    {
    }

    public bool Filter(ISearchContext context, string query, HierarchyProperty objectToFilter)
    {
        var instanceId = objectToFilter.instanceID;
        var obj = Object.FindObjectsOfType<GameObject>().FirstOrDefault(o => o.GetInstanceID() == instanceId);
        return obj != null && obj.name.IndexOf(query, StringComparison.InvariantCultureIgnoreCase) >= 0;
    }
}
```
