Okay, it’s hot off the e-presses: Solr 4.x Deep Dive, Early Access Release #2 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 #2.) My recent blog posts over the past two weeks detailed the changes from EAR#1. A lot of them were formatting and indexing, but a couple more scripting update processor examples, and a new “Solr Hot Spots” preface section to point the reader to interesting sections worth checking out, such as the grammars for the various query parsers, a complete list of functions, and complete lists of char filters, tokenizers, token filters, and update processors. See: http://basetechnology.blogspot.com/ The next EAR will be in approximately two weeks, contents TBD. If you have purchased EAR#1, there is no need to rush out and pick up EAR#2. I mean, the technical content changes were only modest, and EAR#3 will be out in another two weeks anyway. That said, EAR#2 is a significant improvement over EAR#1. -- Jack Krupansky
