Okay, it’s hot off the e-presses: Solr 4.x Deep Dive, Early Access Release #4 is now available for purchase and download as an e-book for $9.99 on Lulu.com at:
http://www.lulu.com/shop/jack-krupansky/solr-4x-deep-dive-early-access-release-1/ebook/product-21079719.html (That link says “1”, but it apparently correctly redirects to EAR #4.) My recent blog posts over the past week detailed the changes from EAR#3, but the main focus was completion of coverage of Solr 4.4 features, in addition to general improvements. I didn’t expect to publish this EAR until next week, but Solr 4.4 came out this week and I was essentially done with 4.4 coverage anyway. I’ll use the extra week so that I can spend next three full weeks trying to focus on a little more deeper coverage for EAR#5 on August 16, 2013. Topic(s) to be decided. See: http://basetechnology.blogspot.com/ If you have purchased EAR#1 or #2 or #3, there is no need to rush out and pick up EAR#4. I mean, the technical content changes were relatively modest (69 new pages), and EAR#5 will be out in another two weeks anyway. That said, EAR#4 is a significant improvement over EAR#1 and EAR#2 and EAR#3. Thanks for your ongoing support! -- Jack Krupansky
