Then it is device specific or country specific? I have a 3rd generation SE on iOS 17, with offline maps downloaded of my region. If the phone is in airplane mode, the search field in Apple Maps turns into a "Browse offline maps" field with no search function. In Organic Maps, the search function is always available (but a bit lacking).
Quite possible that this is region/phone-language-specific.
Many things on iOS are these days: For example, "find things in images" (no idea how it's officially called, identifying animals and places etc.) is available in en_US and de_DE, but not de_US (which I've been using for a while).
