Read the account... there were multiple searches. Not “an internet search” (singular).
Still, there are probably billions of searches a day. They would have to pull searches by IP address, contact the ISP to get the router associated with the IP, figure out which userid owned the router and get a physical address. They would have to do this for every search with that pattern.
It is back to school and canning season. There would be thousands of these searches every day.
