Changing schema and reindexing documents

Hi,

I have lots of documents in my solr index.
Now I have a requirement to change its schema and add a new field.

What should I do, so that all the documents keep working after schema
change?

Thanks

Riz

If you add a field to the schema file and restart Solr, the existing
documents won't have that field. New documents that you index will. If
this is ok, you are safe.

In general, don't change the schema without indexing. You can trip
over the weirdest problems.

You will need to reindex if the schema is changed.
