# Total Viewer

Total Viewer is the key resource for finding desired internal and Total Materia Horizon materials. It provides various [search tool](/total-materia-integrator/total-viewer/search-tools.md) options, allowing users to search for internal materials, [Total Materia Horizon](https://docs.totalmateria.com/) materials, or both.

The core of the search functionality is a three-position slider that lets you instantly control your data source:

* **Internal Materials:** The slider is positioned on the left.
* **Internal and Horizon Materials:** The slider is positioned in the center.
* [**Total Materia Horizon**](https://docs.totalmateria.com/) **materials:** The slider is positioned on the right.

This mechanism ensures you are always searching the correct authoritative source for your needs.
