After you have successfully set up the Solr URL on the Solr Index tab, you can configure search results and metadata display on these tabs:

FAQ
Q. Why are some dates not rendered correctly?
A. On 32 bit systems, the PHP function strtotime() has a limited range. Typically from Fri, 13 Dec 1901 20:45:54 UTC to Tue, 19 Jan 2038 03:14:07 UTC. For more information see this PHP documentation.
Q. Why can't I connect to Solr via https?
A. The Apache Solr PHP Client that we use does not support https connection to Solr. ISLANDORA-646 seeks to remedy this but it is still an unresolved issue.
Q. Why do I get no results for a search for a PID in Advanced Search?
A. You are not using the latest version of Islandora. You used to have to escape the colon in PIDs, but no longer.
