Thanks a lot, those are great examples. I managed to get my cores working. What I noticed so far is that the first (auto-created) core is symlinking files to /etc/solr/... or to /var/lib/solr/...
I now am not sure where my self made-collections should be. Shall I create folders in /usr/share/solr/<collection-folder> and symlink to my files in /etc/solr or can I have hard-copies in my collection-folders? Is /usr/share/solr/ a good place for my collection-folders at all? Am 23.01.2014 12:16, schrieb Alexandre Rafalovitch: > You need config-dir level schema.xml, and solrconfig.xml.
