V.10 - No more autofill in search?

Prior to V.10, when I typed in the search bar, the bar would autofill with the closest or most used match, and a drop down menu would populate with proposed search terms. When I type in the search bar now, there is no autofill. There is a drop down menu, but only of previous search terms I have entered since upgrading to V.10. It was very useful for the search bar to autofill an email address, as that is typically what I am searching for. Was this feature turned off by default with the upgrade? If so, how do I turn it back on?

I lost the search bar when I got V.10. Where did you find it. Please.
Found it finally i a not logical place on the left, and it appears on the top. However, old search was available as soon as I clicked on text field. I hope you can see it too. A search appear on the left, under in boxes, but clicking it has no visible effect.
