This title is so inaccurate it should be changed. Asking who in a city searched for a term is not the same as asking for a whole city's Google searches.

This is equivalent to asking FedEx who in a given city was shipped something from a specific address. Sure when FedEx does a search it may technically search over all shipments from any address, but the government isn't getting access to that information. Hardly equivalent to door-to-door searches of every house.
It is neither equivalent to nor even really analogous to it. It's more like asking a retailer that keeps such records for a list of every purchaser of a specific product.
Which, just to be clear, is something law enforcement will do in some circumstances already.
Sure in the course of getting the answer to that question the retailer may sift through the records of all purchases, but this is data they already have.
This is hardly something to be outraged about. Title implies something much different.
