Just a heads up that we are still working on getting I-Types straightened out, so a few advanced searches may turn up some unexpected results. We have been making changes to the I-Types but so far they have only been made on the load server and not the sandbox.
But this is also great to begin using the standard keyword search function by putting in a combination of term and format. For example search Cats and DVD and you will get your desired result without the extra steps of the advanced search. Better for our customers.
