There is a select where you can choose between 'All', 'My content types' and 'Popular'. I think all of these change the order by weight/criteria in different ways, but I'm unable to comprehend what the 'All' option do.
Make sure you have the blue line below it when you search - this was the reason we added "All" - to make sure user knows he is searching through everything - not just stuff he have installed.
Current "all" is removed"
Current "popular" is renamed to "all"
