Info

This guide is meant to get someone will help you get up and running with a Fedora 4 instance whose updates are automatically indexed in a Solr repository.  This guide glosses over many of the details and should be considered a starting point for testing this feature.  The document assumes a POSIX operating system with curl cURL, a text editor, java Java, git Git, and a download of Apache Solr 4.6.0.

Install and Start Fedora 4

Warning

The fcrepo-message-consumer SolrIndexer implementation does not commit upon updates.  In order to see the changes, you must configure Solr to have a commit strategy that is appropriate for your use.  Node Resource removal events do trigger a commit.
