# Breaking: #63780 - Remove public properties words and word_strings from ReferenceIndex {#breaking-63780-remove-public-properties-words-and-word-strings-from-referenceindex}

See [forge#63780](https://forge.typo3.org/issues/63780)

## Description {#description}

Public properties `words` and `word_strings` have been removed from class `TYPO3CMSCoreDatabaseReferenceIndex`.
`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.

## Impact {#impact}

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

## Affected installations {#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`.

## Migration {#migration}

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