new documents

[Mark Lugert]

Hi Karl,
 
If  I use the sharepoint, alfresco, or cmis repo connectors how can I make it 
only index new documents that match my queries?
 
Right now I'm seeing it reindex everything that matches my query every time the 
job runs.
 
I have it set to scan all documents once, but still rescans everything every 
time I start the job.  Is this a config issue on my part?
 
thanks,
Mark
