I just got done reading http://www.searchworkings.org/blog/-/blogs/uwe-says%3A-is-your-reader-atomic and was specifically interested in the following line
"Unfortunately, Apache Solr still uses this horrible code in a lot of places, leaving us with a major piece of work undone. Major parts of Solr’s facetting and filter caching need to be rewritten to work per atomic segment! For those implementing plugins or other components for Solr, SolrIndexSearcher exposes a “atomic view” of its underlying reader via SolrIndexSearcher.getAtomicReader()." Can someone give more details around this? Is there a JIRA to address this in Solr? I'm assuming that this is not something new, just something that can be improved?
