Modified date values is needed for each file. MS Office's files, pdfs have this value. Problem is with txt files as they don't have this value in their meta. Is there any possibility to get it somehow from os level and force adding it to solr when we do indexing. p.s. Windows 2012 server, single instance typical command we use: java -Dauto -Dc=index_sandbox -Dport=80 -Dfiletypes=vsd,vsdx,xls,xlsx,doc,docx,pdf,txt -Dbasicauth=admin:xxxx -jar example/exampledocs/post.jar "M:\DNS_dump" Regards, Gytis
