Search history is a pretty nice feature to lose unless you volunteer to share your information. I had multiple addresses I had to store elsewhere because Maps would purposely forget them.

I didn't say that you had share location history to get search history, only to sign in. Maybe there was some point in the past where sharing location history was tied to having search history, but I don't remember it, and it's certainly not the case today. If you think that's the case you'll have to provide some third party corroboration.
