As per title,
I do not understand why searching for America does not return the country USA at all, even up to the top 50 results.
What can I do to change this (I think we should return the country USA at least within the top 30 results)? Is there some alias I can add to the database?

This is because so far no one thought about "America" as an alternative name for the United States of America in English. E.g. you got the colloquial name "Amerika" added for some languages as a place name or alternative name, but so far not "America".
So if you do think that "America" is used in English as an alternative for the USA, you might add the alt_name:en=America tag to this relation:
