Solr’s Realtime Get: Increasing its NoSQL Capabilities

From the post:

As readers probably know, Lucene/Solr search works off of point-in-time snapshots of the index. After changes have been made to the index, a commit (or a new Near Real Time softCommit) needs to be done before those changes are visible. Even with Solr’s new NRT (Near Real Time) capabilities, it’s probably not advisable to reopen the searcher more than once a second. However there are some use cases that require the absolute latest version of a document, as opposed to just a very recent version. This is where Solr’s new realtime get comes to the rescue, where the latest version of a document can be retrieved without reopening the searcher and risk disrupting other normal search traffic.
