| **Track the current selection in the search**           | Enable this setting to execute the [`SearchProvider.trackSelection`](/engine/6000.0/manual/unity-editor/editor-navigating-managing/editor-searching/search-overview/create-search-provider/api-register-provider.md) callback each time the Search selection changes.The callback *pings* Assets in the Project window or Hierarchy window, which can slow Search navigation in large Projects.                                                   |

| **Search Engines**                                      | Set the search fields in the [Object Selector](/engine/6000.0/manual/working-with-gameobjects/unity-components/inspector-manage-components/search-advanced-object-picker.md), [Project](/engine/6000.0/manual/searching.md), and [Scene](/engine/6000.0/manual/searching.md) to one of the available search engines.**Classic** - The original search functionality.**Advanced** - The latest version of Search for Unity (formerly QuickSearch). |
