Actually "usa" already matches United States it is just quite far down the list.

Matching is handled by the fuzzy library which is a dependency of svelte-typeahead which means it's out of our control unless we either:

• submit a PR to fuzzy adding support for better matching
• fork svelte-typeahead and switch to a better fuzzy search library (there's a few)
• create our own typeahead combobox from scratch

All of those are in the "too hard basket" for now at least.

What I have done though is made it so we can hand curate a list of countries where we use the official name instead of the common one in case it's better, currently that list just includes USA. Usually common is better but in the case of USA, common is United States and official is United States of America. This way at least "america" will find it.
