We've seen at least two cases in user research of users being confused by the country Czechia when searching for The Czech Republic. The country name changed in April 2016, but this is probably not well known.

From the user's point of view, neither is correct. The first they've never heard of, and the second doesn't exist any more (but people may still think it more relevant). The second probably shouldn't show unless services explicitly want historic countries.
If the user types the full name they know, it works better:
This is better, but unless they type enough characters, they don't get the name they're familiar with.
Possible solution
When a country name changes, for a period of time after that (3-5 years?), show the historic name as well:
This feels like quite a nice use of registers - the correct current name is used, but users are 'eased' in to the new name.
