: I then tried to locate some config somewhere that would specify that the : default core would be collection1, but could not find it.
in the older style solr.xml, you can specify a "defaultCoreName". Moving forward, relying on the default core name is discouraged (and will hopefully be removed before 5.0) so it's not possible to configure it in the new core discovry style of solr.xml... https://cwiki.apache.org/confluence/display/solr/Solr+Cores+and+solr.xml For now owever, the hardcoded default of "collection1" is still used for backcompat when there is no "defaultCoreName" configured by the user. and things like post.sh, post.jar, and the tutorial have not really been updated yet to reflect that the use of the default core name is deprecated. : 2) I ran across SOLR-545 which seems to imply that the current behavior : (dispatching the update requests to the core named collection1) is a bug Yeah, A lot of things have changed since 1.3 ... not sure when exactly the configurable defaultCoreName was added, but it was sometime after that issue i believe. -Hoss http://www.lucidworks.com/
