Not much more to add than my post here! This book is targeted towards Lucene-based search (Elasticsearch and Solr) relevance.
Announcement with discount code: http://opensourceconnections.com/blog/2016/06/21/relevant-search-published/ Related hacker news thread: https://news.ycombinator.com/item?id=11946636 Thanks to everyone in the Solr community that was helpful to my efforts. Specifically Trey Grainger, Eric Pugh (for keeping me employed), Charlie Hull and the Flax team, Alex Rafalovitch, Timothy Potter, Yonik Seeley, Grant Ingersoll (for basically teaching me Solr back in the day), Drew Farris (for encouraging my early blogging), everyone at OSC, and many others I'm probably forgetting!
