When i try to add a standard Search web part to my home page i cannot see the category search. In one of my site collections it is available, but in the other site collection it is not. Now i know it is propably something i have to activate, but i have been looking a lot now and can't seem to find it. Below is an image to further explain my problem.
Thanks in advance!
Edit So the answer below is correct, the reason why i did not find it by myself because I was logged in as a user with full control but not site colelction admin. So i did not see this option, so for future reference, don't make the same mistake!
