Hi Andrea, really curious I found the province where I was born in the Solr mailing list :)
Apart that , based on your requirements, it's not possible to use any suggester. You should definitely design a new Solr collection(core) for your requirements. Would be quite easy to provide those services through a new specific Solr core.
