My Ipad keep "searching for update......." but never showed or got to anything. Any ideas, guys?

End the search, you will only wear the battery down and tie up the iPad.

Connect to your computer in iTunes. Make sure the computer is updated. Update all apps.

Go to summary page for your iPad and back up then select the update.

It shouldn't take very long, , less than 30 minutes on an Apple computer, not sure how long on a windows PC.
