Even thaw it start of with a history introduction to Solr, and the title of the book is Beginner's Guide, don't be fooled by that. This book is so much more that that, it quickly takes up a "Hand-On" approach and will gradually make you test out all the chapters one by one. Things to be mentioned as followed: Indexing with Local PDF Files indexing an example document with cURL playing with spell-checks prototyping an auto-suggester with facets Working with Multiple Entities, Multicores, and Distributed Search
It basically has a bit of everything and combines them so well that no matter if you come from PHP or any other programming languages you will have a easy time understanding this book and going throw its examples with a breeze in the same time expanding your knowledge base.
The last days, I 've read the book "apache sold beginners Guide". The book starts with knowledge for beginners and describes how to install Solr on windows, linux and mac. With lots of examples, you can understand the operation of Solr. Another big part of the book is dealing with searching function. The book tells you also about extending search, faceted search and distributed search. The book is a very good partner for starting with Solr. It's extremely readable and I can thoroughly recommend this book.
The reason I'm giving it just one star is it's for Solr 4.x, not the current version 5.4.1 (January 2016). This wasn't apparent in the Product details and also there is a 2nd. edition due out on 1st. April 2016, which covers version 5. This should have been made clear and I would have purchased a Solr 5 book.
It maybe an excellent book for Solr 4 but not for what I wanted.
As usual Amazon's excellent customer service prevailed and I returned it for a credit.
