Breaking: #63780 - Remove public properties words and word_strings from ReferenceIndex

See forge#63780


Public properties words and word_strings have been removed from class \TYPO3\CMS\Core\Database\ReferenceIndex. ReferenceIndex->words was always an empty array and ReferenceIndex->word_strings contained strings from input- and text fields of every record that was given to this class instance.


An extension relying on one of these public properties will fail.

Affected installations

It is unlikely that any extension used the properties words or word_strings. An instance could be checked by searching for usages of class ReferenceIndex.


The according logic needs to be re-implemented in an extension that used the content of these properties.
