Version 3.1 problem with partial country searches

Hi, I am developing a little app for learning purposes. We want to show suggestions based on partial country name. For example I understand if I search "ho", I should get results like "Hong Kong, Honduras..." countries which contains "ho" string.

But, why do I get such strange results like Japan?

For example, in postman:

https://restcountries.com/v3.1/name/ho?fields=name

I get such response. Why do I get countries like Noth Korea or Japan or such with no "ho" on none of their names? Maybe is looking on all the fields for the string, and not only in the name field? Can´t get it.
