Solr will use the stored fields along with the updates you provide to produce a complete version of the document concerned. If you don't store them, they can't be retrieved in this way, and your field values will disappear. Therefore, you need to store a field for it to survive an atomic update. Whether you index it or not is up to you and the needs of your application. Upayavira
