Jegan By DIH Scheduler you mean http://wiki.apache.org/solr/DataImportHandler#Scheduling ? If so, then it's not yet in. More details in the Ticket (which is as well linked from the Wiki-Page): https://issues.apache.org/jira/browse/SOLR-2305
Regarding your Question on the UI: the "Auto-Refresh" Checkbox only automatically updates the status you're seeing on the screen. So for example while you have running a import, you can activate this checkbox and relax in your chair while the screen updates itself every two seconds - but that does neither trigger a import itself nor does it (initiate) anything else beside fetching status information HTH= Stefan On Tuesday, March 19, 2013 at 7:32 PM, Jegannathan Mehalingam wrote: > Is the DIH Scheduler available in SOLR 4.1 or in 4.2?
