SQL Server 2008 includes word breakers for approximately 50 languages, of which 23 also exist in SQL Server 2005. Only the word breakers for English, Korean, Thai, and Chinese (all forms) remain the same. For the other languages, SQL Server 2008 introduces a new generation of word breakers that work substantially better than their SQL Server 2005 equivalents. Potentially, the new word breakers might behave slightly differently from SQL Server 2005 word breakers. For information about updating word breakers after importing a SQL Server 2005 full-text index, see Word Breakers and Stemmers.
To create a noise word (stopword) list for a language, the language be registered with SQL Server.
Thesaurus files are automatically loaded by full-text queries that use the thesaurus. To avoid this first-time performance impact on full-text queries, we recommend that you execute sp_fulltext_load_thesaurus_file.
To update the list of languages registered with full-text search, use sp_fulltext_service 'update_languages'.
