Kurzbeschreibung

In Detail

With over 40 billion web pages, the importance of optimizing a search engine's performance is essential.


Solr is an open source enterprise search platform from the Apache Lucene project. Full-text search, faceted search, hit highlighting, dynamic clustering, database integration, and rich document handling are just some of its many features. Solr is highly scalable thanks to its distributed search and index replication.


Solr is written in Java and runs as a standalone full-text search server within a servlet container such as Apache Tomcat or Jetty. Solr uses the Lucene Java search library at its core for full-text indexing and search, and has REST-like HTTP/XML and JSON APIs that make it usable with most popular programming languages. Solr's powerful external configuration allows it to be tailored to many types of application without Java coding, and it has a plugin architecture to support more advanced customization.

With "Apache Solr Beginner's Guide" you will learn how to configure your own search engine experience. Using real data as an example, you will have the chance to start writing step-by-step, simple, real-world configurations and understand when and where to adopt this technology.


"Apache Solr Beginner's Guide" will start by letting you explore a simple search over real data. You will then go through a step-by-step description that gives you the chance to explore several practical features. At the end of the book you will see how Solr is used in different real-world contexts.


Using data from public domains like DBpedia, you will define several different configurations, exploring some of the most interesting Solr features, such as faceted search and navigation, auto-suggestion, and rich document indexing. You will see how to configure different analysers for handling different data types, without programming.

You will learn the basics of Solr, focusing on real-world examples and practical configurations.

Approach

Written in a friendly, example-driven format, the book includes plenty of step-by-step instructions and examples that are designed to help you get started with Apache Solr.

This book is an entry level text into the wonderful world of Apache Solr. The book will center around a couple of simple projects such as setting up Solr and all the stuff that comes with customizing the Solr schema and configuration. This book is for developers looking to start using Apache Solr who are stuck or intimidated by the difficulty of setting it up and using it.

For anyone wanting to embed a search engine in their site to help users navigate around the mammoth data available this book is an ideal starting point. Moreover, if you are a data architect or a project manager and want to make some key design decisions, you will find that every example included in the book contains ideas usable in real-world contexts.

5.0 von 5 Sternen Gutes Buch für den Einstieg mit Solr 27. April 2014
Format:Kindle Edition
Das Buch fängt bei Null an und beschäftigt sich mit gleich zu Beginn mit der Installation von Solr auf den Plattformen Windows, Linux und Mac. Anhand von Beispielen kann die Funktionsweise von Solr nachvollzogen werden. Neben dem Indizieren von PDFs wird auch das Indizieren von Webseites behandelt. Ein großer Teil des Buchs beschäftigt sich auch mit der eigentlichen Suchfunktion. Auf das Thema Queries, erweiterte Suche und Facettensuche wird in dem Buch sehr gut eingegangen. Wer sich mit dem Thema Solr beschäftigen will, findet mit dem Buch einen sehr guten Einstieg.

5.0 von 5 Sternen It Lives up to "Learn by Doing" approach 7. April 2014
Von A. Pamulapati - Veröffentlicht auf Amazon.com
Format:Taschenbuch
I work as a search engineer implementing solutions for various clients, i started on Solr about a year ago, so i picked up Apache Solr Beginner's Guide to make my understanding of Solr well rounded. I am a hands on person and do not settle for theory. From the beginning Apache Solr Beginner's Guide lived up to the motto of "Learn by Doing". Firt chapter quickly introduces you to kick tires with Solr and start playing. Second chapter to index PDF files, which tend to be bigdeal for lot of beginners for some reason i see a lot of questions on this topic on Stackoverflow. Next chapter goes on to introduce basic search based on large test data indexed from Wikipedia style data. Once the basics are set your footing they change gears and put on to what we all developers really care - customizations by extending search , faceted search, distributed search with usecases . Examples of Customization like detecting language with Tika are very intuitive . They gave huge collection of client integration examples including open source carts like Magento e-Commerce. I wish there is more material on customizations with examples, but they prepare you well for you in that path to explore. I highly recommend any Beginner to start their Solr learning with this book to complement lot of material out there on the internet. I downloaded code examples from here : <a href="bit.ly/1lYX0ij">bit.ly/1lYX0ij</a> under support tab.

5.0 von 5 Sternen Great place to start 25. Mai 2014
Von Stefan Christian Ritter - Veröffentlicht auf Amazon.com
Format:Taschenbuch
This book is way more than just a beginner's guide. We are using a hosted Solr solution at work and I must say this is the best intro to Solr I've come across so far - even though I've been using Solr already a bit, I've learned a great deal from this book and it's example based approach. Open source projects can be really hard to get started with because the community moves so fast, I wish I would have had this book when I got started.
The book is structured very well in a clear and concise manner. Each chapter starts with a practical problem like 'Indexing with local PDF files' or 'Using faceted search' it then first discusses the problem and the Solr way of solving it. After that the author walks you through the commands so you can test the solution immediately yourself. I highly recommend reading this book next to a computer so you can fire up your terminal any time and get the most out of its 'learning by doing' approach. Because of the book's example based structure it has also been a good resource for me to go back to at work - the Solr documentation lacks examples almost entirely, which makes this book a great desk companion.

5.0 von 5 Sternen Way to go to Apache Solr 7. April 2014
Von Pekka Ollikainen - Veröffentlicht auf Amazon.com
Format:Taschenbuch
I was total newbie with Apache Solr but I do have some Java studies at my past This was given me good background start to dive into world of this book. I actually like Apache Solr and book very much and it is giving me good learning experience on issues of how to conduct full-text search, faceted search etc.in practise at Java backend - and overall gives good beginners view of what kind of results one could reach at their web sites/appliucations by putting engine such as Apache Solr under the hood of their Java (web) installation. As soon as you manage to do your local installation of Solr , book will give you plenty of good receipts and will teach your basic concepts of how to conduct your own search engine with Solr.

5.0 von 5 Sternen Great as a decision help as well as a jump start to using Solr productively 3. April 2014
Von Stephan Hochhaus - Veröffentlicht auf Amazon.com
Format:Taschenbuch
For a project I needed to introduce search capabilities that would have killed my usual SQL-based approach. By accident I stumbled across this book and used it as a basis to decide whether to use Solr in my project. Bottom line: Solr is awesome and this book is an excellent introduction that will get you going quickly.

Coming from PHP I wasn't too keen to introduce any Java components in my deployments as I wasn't sure how they would integrate and whether they'd play nicely, but they sure do. This book covers Solr 4.5.0 and works quite well also for the most recent 4.7.0 release. At least I couldn't find any situations where it was wrong.

You will learn from this book how to create your own searches, index/import data from different sources (web, pdf and cdv files, databases), configuring tokenizers and tweaking search to suit your needs, geolocalization, and much more. This book goes beyond the simple beginner's topics and also addresses deployments with multiple instances (SolrCloud) and how to integrate with other systems such as Alfresco or even Wordpress.

The only downside I found is that the examples used in the book (and provided in full as a download) are a bit complex so you have to spend a little bit of time to replicate the environment to fully follow the book. On the other hand it provides an even better understanding of how things work together. Since many of the code examples are using XML it is very hard to read in the printed version of the book. Unfortunately the epub version does not support syntax highlighting so I suggest you go through code examples directly in an editor that supports syntax coloring.

I'd suggest the Apache Solr Beginner's Guide to anyone considering to use advanced search technology in general or Solr in specific and want to get a good and broad overview of its capabilities. It is as much hands-on as it covers all relevant areas.

4.0 von 5 Sternen Grand Book 19. März 2014
Von Pule Nong - Veröffentlicht auf Amazon.com
Format:Taschenbuch
Apache Solr is an open source full-text search server written in Java. This book is billed as being for anyone who has the will to learn.
The author asserts that no prior programming experience is required. In my opinion, prior programming knowledge is a necessity to follow along.On page 68 of the book the author states that "both XML and json are widely used on Internet applications and mashups, so I suggest you become familiar with both of them." One can only be fully familiar with these afore-mentioned technologies only when one has some sort of programming knowledge. Knowledge of using the command prompt is also important.

Other than that I think this is an awesome book that demonstrates the limitless possibilities one can venture into using Apache Solr. Even after completing this book I find myself going through it again so as to familiarize myself more with Apache Solr. There are a lot of topics covered in this book. These include among others:

- How to install Apache Solr
- Using faceted search
- Working with Multiple Entities, Multicores, and Distributed Search
- Collecting the paintings data from DBpedia
- Indexing with Local PDF Files

The positive to take away from this book is that it is written in a manner that is easy to understand. So there is no need to have a dictionary close by. It is written in a practical manner. You get to see how covered concepts are applied. If you are focused enough you will be just fine in following along.
I highly recommend this book to anyone who needs to incorporate a full-text search engine to their application. In terms of rating this book I give it a 4/5 rating.
