Thanks.. I got this concept bit clear. while using deltaimport in solr 4.x specifically the automatic update feature will add new document to the index with updating latest value into the field(because we use the_version_ field in our schema).Therefore we will have two results with different _version_ numbers.
the question is how do i clear the previous result from the index (delta-import with clean= true will clear all the index) ??????? -- View this message in context: http://lucene.472066.n3.nabble.com/Solr-4-2-automatic-DB-updates-for-sync-using-Delta-query-DIH-with-scheduler-tp4051114p4051394.html Sent from the Solr - User mailing list archive at Nabble.com.
