First off I just want to say that these queries were a great help. I'm not sure which version of SQL Server you are working with, but I am working in SQL Server 2008. I ran your queries as listed and found no data. It turns out in SQL Server 2008 the tables that you need to query are msdb.dbo.sysssispackages and msdb.dbo.sysssispackagefolders.
I should have been more clear that my code in the article that that the example was for SQL 2005. I assume that if you change the table names in the query for SQL 2008 that the search works in 2008?
