Using SQL 2005 Management Studio...
I renamed a stored procedure and clicked "reindex", it seemed to reindex. But when I search for the old name, the stored procedure is still returned in the result and has the old text (with the old name). Searching for the new name returns the same (with the old name after CREATE PROCEDURE). If I click "Select object in Object Explorer" it takes me to the renamed (now with new name) stored procedure in the object explorer.
I'm not sure if the lifetime of the index is for the duration of sql management studio but I haven't restarted mine so I can't confirm that.
Otherwise, this is a very simple and easy to use tool that offloads the work I have to do to search for terms in my procedures.
