# Breaking: #75349 - Move Indexed Search pi-based plugin to compatibility7 {#breaking-75349}

See [forge#75349](https://forge.typo3.org/issues/75349)

## Description {#description}

The Extbase plugin (pi2) stays in Indexed Search as before.

Installation of EXT:compatibility7 is required to continue using the pi1 plugin. In the longer run migrating to the Extbase plugin is required.

All installations using the pi-based indexed search plugin.
