On MS SQL 2008 databases, Full-Text indexing is already enabled on the database. For MS SQL 2005 please contact us with the request and your database name and database server name so we can enable it if needed on your specific database.
You would then create your full text catalog either through SQL Management Studio or using SQL queries.
