Takes a little adjustment, but you can do quite a bit of good work without Google (or any search).

Spoken from a fair bit of experience doing software development in closed rooms with strict control of all digital devices (from your phone to your watch) and absolutely no external connections.

There are moments that are painful still, because you'll be trying to find a thing in a manual and you know a search can get it faster - but it's silly to imply this isn't possible.
