The patch in SOLR-5408 fixes the issue with sorting only for two sort fields. Sorting still breaks when 3 or more sort fields are used.
I have attached a test case, which demonstrates the broken behavior when 3 sort fields are used. The failing test case patch is against Lucene/Solr 4.7 revision number 1602388 Can someone apply and verify the bug ? Also, should I re-open SOLR-5408 or open a new ticket ? --- Thanks & Regards Umesh Prasad
