Hello, The CoreAdmin wiki page (http://wiki.apache.org/solr/CoreAdmin) implies that setting up at least one core is not mandatory and neither is solr.xml. However when trying to migrate from 3.6 to 4.0 beta, I got a message in the admin console: "There are no SolrCores running — for the current functionality we require at least one SolrCore, sorry :)"
Here are a few questions that probably need to be cleared up in the documentation. 1) Is running at least one core required or is the message above referring to some admin console functionality that wont work without at least one core? If running at least one core is required, perhaps this needs also to go in the Release notes/Changes. 2) The README.txt file in example/solr/README.txt needs revision. Is example/solr the Solr Home directory? If so what is the relationship between Solr Home and subdirectories for different cores? Do only lib files go in /example/solr/lib or in example/solr/collection1/lib Which files/directories are shared by cores and which need to be in separate core directories? I'll be happy to add these as a comment to Solr 3288 if that is appropriate. Please let me know. Thanks for all your work on Solr 4! Tom
