Deprecation: #78679 - Crawler inclusion via require_once in Indexed Search

Description

The system extension "Indexed Search" has support for EXT:crawler, by using the crawler library to index a page.

This functionality is done under the hood via the Indexer class, which does a manual PHP call on "require_once" - code which is not necessary anymore, since the TYPO3 Core class loader is in place. The public PHP method TYPO3\CMS\IndexedSearch\Indexer->includeCrawlerClass() is therefore marked as deprecated.

Impact

Calling the method TYPO3\CMS\IndexedSearch\Indexer->includeCrawlerClass() will trigger a deprecation log entry.

Affected Installations

Any TYPO3 installation with a custom indexer written in PHP, and Indexed Search and Crawler installed, and the custom indexer using the method call above.

Migration

Remove the function call, as TYPO3 includes the PHP class automatically.
