Breaking: #68354 - Uniform extension directory structure of EXT:indexed_search¶
See Issue #68354
The directory structure of the extension “Indexed Search” has been streamlined.
All language files are now located in directory Resources/Private/Language, the template files in Resources/Private/Templates. Icons from pi/res directory have been moved to Resources/Public/Icons, images to Resources/Public/Images.
Installations that use EXT:indexed_search that depend on paths that have been moved.
Make sure your configuration matches with new directory structure.
