Answer 1

Why would you have two stemmers?
Try removing EnglishPorterFilterFactory (deprecated) from both of your analyzer types, rebuild the index and then try whether search for American will yield America.

If that wont work, the other thing you can try is to remove both of your stemmer filters and add SnowballPorterFilterFactory with language="English" instead.
