I would be very surprised if there way a law requiring search history to be recorded.

Just because some data can be supoenaed doesnt mean you are required to store/create the data in the first place.

I agree, search history is a bit too specific to be encoded in laws. There are, however, a broad class of laws called "mandatory data retention" laws, which the EFF is against. https://www.eff.org/issues/mandatory-data-retention
