I take your point - but if you cannot find the on-device Search, there are some other search options should they be needed 🙂
The User Guide, for some unfathomable reason, is never installed by Apple on new devices. It’s an excellent (and regularly updated) publication that gives great insight. It’s a resource totally overlooked by the majority of end-users.
Whenever a major OS update appears, I always advocate finding the new User Guide in the Bookstore - and downloading it. Then if anything goes wrong, won’t connect to WiFi or the internet, or other help is needed - then it is close to hand. If nothing else, for many, reading through the early pages answers all those “how do I do this” type questions - of which our friendly forum fills whenever something new comes along. The contributors here are always willing (if not always able) to help where we can - but there are much faster (and sometimes more reliable) ways to get quick answers or resolution to a user issue.
there are many changes to both the UI and the gestures within iPadOS/iOS13 - and like all the controls, once introduced become second nature. We don’t always “like” some of them, but at least we can get to core functions (such as search) without too much hassle.
Anyway, genuinely and from the heart, I strongly recommend downloading the User Guide for reference. You’ll find them for every major version of iOS for both the iPad and iPhone. For the most part, they really are a lifesaver. There is also an online version - although, ironically, it’s not quite as friendly or searchable 🙂
