Not getting any results!

I created my first post after the update and am not getting any results returned when I search. I have tried several search terms, including ones that have worked before. My settings are:

How many posts maximum = 5
Select post types = Posts
Randomize related posts = You can randomize the posts request AND
            You can randomize the display for posts order.
Display mode = List Mode
Display content? = unchecked
Use auto related posts? = unchecked
