Revert the Word Breakers Used by Search to the Previous Version

  • Artikel

SQL Server 2012 installs and enables a new version of the word breakers and stemmers for all languages supported by Full-Text Search with the exception of Korean. This topic describes how to switch from the new version of these components to the previous version, or to switch back from the previous version to the new version.

For information about the changed behavior of the new components, see Behavior Changes to Full-Text Search.

This topic does not discuss the following languages:

  • English. To revert or restore the English components, see Change the Word Breaker Used for US English and UK English.

  • Danish, Polish, and Turkish. The third-party word breakers for Danish, Polish, and Turkish that were included with previous releases of SQL Server have been replaced with Microsoft components.

  • Czech and Greek. There are new word breakers for Czech and Greek. Previous releases of SQL Server Full-Text Search did not include support for these two languages.

  • Korean. The word breaker and stemmer for the Korean language are not upgraded in this release.

For general information about word breakers and stemmers, see Configure and Manage Word Breakers and Stemmers for Search.

Languages for which neither the previous nor the current file name is NaturalLanguage6.dll

For the languages in the following table, the file names of the previous word breakers and stemmers are different from the file names of the new versions. Neither the previous nor the current file name is NaturalLanguage6.dll. You do not have to replace any files, because SQL Server 2012 setup copies both the current and the previous versions of the components to the Binn folder. However you have to change a set of registry entries to specify the previous or current version of the components.
