Apache Solr Enterprise Search Server, 3rd Edition
David Smiley, Eric Pugh, Kranti Parisa, and Matt Mitchell are proud to finally announce the book “Apache Solr Enterprise Search Server, Third Edition” by Packt Publishing. You can find links to buy it at Packt’s site & Amazon from our book’s official website: solrenterprisesearchserver.com. You'll find a useful search parameter quick-reference sheet (the appendix) online there too.
Apache Solr Enterprise Search Server, Third Edition is a comprehensive resource to almost everything Solr has to offer. It serves the reader right from initiation to development to deployment. It also comes with complete running examples to demonstrate its use and show how to integrate Solr with other languages and frameworks — even Hadoop.
By using a large set of metadata, including artists, releases, and tracks, courtesy of the MusicBrainz.org project, you will have a testing ground for Solr and will learn how to import this data in various ways. You will then learn how to search this data in different ways, including Solr's rich query syntax and boosting match scores based on record data. Finally, we'll cover various deployment considerations to include indexing strategies and performance-oriented configuration that will enable you to scale Solr to meet the needs of a high-volume site.
Solr 4 was Solr's biggest release ever. We updated the previous edition to cover Solr 4, and some of Solr 5 -- particularly the part of Solr 5 that needs to be covered most, the bin/solr script. Chapter 9, Integrating Solr, now covers Hadoop integration, and better covers SolrJ. Chapter 3, Text Analysis, introduces various approaches for implementing Multilingual Search in your applications. And we think you'll appreciate the enhanced coverage of the topic of query auto-suggesters (AKA query completion) in Chapter 8, Search Components -- a feature that is important to most search applications. This edition has two additional authors, Kranti & Matt, who add their perspectives based on their experience working with Solr for a long time.

Apache Solr Search Patterns
Jayant Kumar is proud to announce the book "Apache Solr Search Patterns" by Packt Publishing. This book is for developers who have prior knowledge on Solr and are looking at procuring advanced strategies for improving their search using Solr. Also, if you work with analytics to generate graphs and reports using Solr and you are a search architect who is looking forward to scale your search using Solr, then this book is a perfect guide for you.
Apache Solr Search Patterns begins with a brief introduction of analyzers and tokenizers to understand the challenges associated with implementing large-scale indexing and multilingual search functionality. It then moves on to working with custom queries and understanding how filters work internally. While doing so, it also helps the readers create their own query language or Solr plugin that does proximity searches.
Furthermore, the book discusses how Solr can be used for real-time analytics and tackle problems faced during its implementation in e-commerce search. It then dives into the spatial features such as indexing strategies and search/filtering strategies for a spatial search. And also do an in-depth analysis of problems faced in an ad serving platform and how Solr can be used to solve these problems.
