Revert the Word Breakers Used by Search to the Previous Version
SQL Server 2014 installs and enables a 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 this version of these components to the previous version, or to switch back from the previous version to the new version.
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.
Overview of reverting and restoring word breakers and stemmers
The instructions for reverting and restoring word breakers and stemmers depend on the language. The following table summarizes the 3 sets of actions that may be required to revert to the previous version of the components.
| Current file | Previous file | Number of affected languages | Action for files | Action for registry entries |
|---|---|---|---|---|
| NaturalLanguage6.dll | NaturalLanguage6.dll | 34 | Obtain and install a previous version of NaturalLanguage6.dll, overwriting the current version of the file. | No action required. The registry keys and values have not changed for this release. |
| (Other file name) | NaturalLanguage6.dll | 5 | Obtain and install a previous version of NaturalLanguage6.dll, overwriting the current version of the file. | Change a set of registry entries to specify the previous version of the components. |
| (Other file name) | (Other file name) | 6 | No action required. SQL Server 2014 setup copies both the current and the previous versions of the components to the Binn folder. |
Change a set of registry entries to specify the previous version of the components. |
Warning
If you replace the current version of the file NaturalLanguage6.dll with a different version, then the behavior of all the languages that use this file is affected.
The files described in this topic are DLL files that are installed in the MSSQL\Binn folder for the SQL Server instance. The full path is typically the following path:
C:\Program Files\Microsoft SQL Server\<instance>\MSSQL\Binn
Languages for which the file name of both the current and previous word breaker is NaturalLanguage6.dll
For the languages in the following table, the file name of both the current and previous word breaker is NaturalLanguage6.dll. To revert or restore these components, you have to overwrite NaturalLanguage6.dll with a different version of the same file. You do not have to change any registry entries, because the registry entries have not changed for this release.
Warning
If you replace the current version of the file NaturalLanguage6.dll with a different version, then the behavior of all the languages that use this file is affected.
