Well, if you are changing query analyzer chain, you can get away without reindexing.
But if you change index analyzer chain, then your older tokens are stored in a different ways. Even if Solr does not complain, it will not match and may lead to very obscure issues. And if you change the type radically (String to text or to integer), I am quite sure Solr will complain a lot.
