I had installed sql server 2008 express edition with tools but I need to use full text search which i understand is missing in the edition that I have.
How do I go about upgrading to get full text search feature? As it was an online installation I don't have any installation media stored on my computer
Can I use something else?
There is a downloadable version of SQL Server 2008 Express Edition with Advanced Tools which does include full text indexing. Freely downloadable from Microsoft web site.
