I don't think there's a synonym file for this use case. I am not even sure if
synonym is the right way to handle it.
I think the better way to improve recall is to mark up your documents with
a hidden field of is the geographic relations. For example, before indexing,
you can add a field to all documents containing South America, something
like: South America is a subcontinent, that is consisted of the countries
Brazil,
Chile, Argentina, …
This data can come from various sources, such as wikipedia, wordnet, etc.

No I have already thrown together a list of countries and continents
however I'm a little more ambitious,
I would like to get a lot more regions such as american states as well or
Former members of the USSR...
Are there ready made synonym files or taxonomies in a different format.
Are synonyms the best way of achieving this? Perhaps there is a better way?
Any pitfalls or advice on this subject from someone who has done this
before would be appreciated.
Thanks
