It really depends on the change. Typically, adding fields is fine,
but of course, it means that you will only be able to search those
fields in the new documents. Other changes often require re-
indexing. Change the semantics of a field (i.e. changing FieldType)
will require re-indexing.
Preface: This is my first attempt at using solr.
What happens if I need to do a change to a solr schema that's already
in production? Can fields be added or removed?
Can a type change from an integer to a float?
Thanks in advance,
Jon
