I can not find the search bar after I downloaded the IPADOS?

Reboot your iPad and see if it works after you get back in.

• iPad models with Face ID: Press and quickly release the Volume Up button. Press and quickly release the Volume Down button. Then press and hold the Power button until the device restarts.
• iPad with Home button, iPhone 6s or earlier, and iPod touch (6th generation) or earlier: Press and hold both the Home and the Top (or Side) buttons until you see the Apple logo.

Hi, this is a very common question. You need to start in the middle (mid way from top and bottom and left and right) and swipe down. In fact you can start anywhere on the screen as long as you are no where near the edge.

Search bar for what exactly? If you mean spotlight search, on the iPad screen, swipe down from the middle of screen.

Try the restart and if that doesn't click on the link at the bottom which tells you how to reboot if you don't know how.

Um, that's EXACTLY what I suggested in my first reply to you! :-)

Nobody mentioned starting from the top!

Go to the home screen, then from the middle of the screen, swipe down. Seems like a strange method, but oh well.

I found the answer here in the discussions on another thread.
