Subject [Solr Wiki] Update of "NearRealtimeSearch" by Mark Miller
Date Sun, 04 Sep 2011 18:50:05 GMT
Dear Wiki user,

You have subscribed to a wiki page or wiki category on "Solr Wiki" for change notification.

The "NearRealtimeSearch" page has been changed by Mark Miller:
http://wiki.apache.org/solr/NearRealtimeSearch?action=diff&rev1=14&rev2=15

  
  Near realtime search will be added to Solr in version 4.0 and is currently available on
trunk.
  
- You can now modify a commit command to be a 'soft' commit. A soft commit will avoid parts
of the standard commit that can be costly. You still will want to do normal commits to ensure
that documents are on stable storage, but soft commits allow users to see a very near realtime
view of the index in the meantime.

settings as they can have a significant impact on NRT performance.
