I have a solr core having 2 million lengthy documents. 1. If I modify datatype of a field 'foo' from string to a sint and restart the server, what would happen to the existing documents? And documents added with the new schema? At query time (sort=foo desc), should I expect the documents sorted properly?
Do I need to re-index all documents? 2. If I add two additional fields, do I need to re-index again? Thanks.
