Recently, Microsoft added Full Text search capabilities to MS SQL Express 5000 in a packaged titled Advanced.  It simply indexes one or more fields based on text words making it quick to find a record containing certain keywords.

While I have worked some with Full Text abilities in SQL Server 2005 Enterprise, I have not used them through the SQL Server Management Studio Express.  It appears Full Text features were not originally supported and you need SQL SP2 to obtain any of the features.

Here is a good post on Full Text features in SQL Server 2005 Express by hand on:
