Subject Re: solr as the data store
Date Wed, 28 Jan 2009 21:59:28 GMT
I am planning with backups, the recovery will only be incremental.

Is there an internal field to know when the last document hit the index or
is this best to build your own "created_at" type field to know when you need
to rebuild from?

After the backup is restored, this field could be read and then the restore
from that time could kick in.
