Lucene in Action: Covers Apache Lucene v.3.0

Excellent pedagogical maiden level text book, which you can use to write some custom code for your search needs.I found it well-written, with clear and concise guidelines on writing your own custom analyzer.Highly recommended, if you are working on implementing / improving your application's search feature.

Conoscevo questo libro già prima di acquistarlo, si puo dire che sia la bibbia per fare information Retrieval con uno strumento come Lucene.

Excellent book on Lucene. After finishing it, I was able to customize Lucene successfully.

- Sehr gute Einleitung (mit Beispielen).- Sehr ausführliche Erklärung der Basics (z.B. Was ist ein Analyzer und wie beeinflusst er den Inhalt des Suchindexes? Prefixsuche, Fuzzy-Logic? Query-Syntax, Highlighting der Suchergebnisse?..)- Sehr verständlich und locker geschrieben.- Passende Anwendungsbeispiele (auch für nicht ganz so leicht zu verstehende API-Funktionen).- Ist zwar für Java-Entwickler geschrieben, ließ sich aber fast 1:1 auf die Lucene.Net-Version anwenden, da API nahezu identisch (vielleicht ein paar Ausnahmen mit Contrib-Modulen z.B. Token basierende N-GRAM Analyse - aber - Hey, wer so weit geht findet das auch alleine raus ;-)Wem die technischen Hintergrundinformationen zu oberflächlich sind, dem empfehle ich "Jewels of Stringology" von Maxime Crochemore und Wojciech Rytter.Fazit: hervorragendes Buch zur Einführung in Lucene auch für .Net-Entwickler (Lucene.Net einfach via NuGet installieren und los geht's..)

I found the book an excellent complement to more academic texts on information retrieval and document indexing. Code examples are relevant to real-world problems and simple enough to get a working prototype up and running quickly. More advanced techniques and the theory behind them are clearly explained and point the motivated reader in the right direction for further study.

I think the overall rating for this book is at 4.0, only because of some people using the older first edition and finding that it is already out of date. Also it would be nice if amazon separates product ratings from the shipping/supplier ratings, because the book's rating unfortunately suffers because of a bad shipment rating!I was waiting eagerly for the 2nd edition and it is out now. It is written extremely well. It still has the same flow, clarity and style as the first edition. If you need to know lucene well, then the 2nd edition is a must-have! It also has lots of new chapters (like the one on tika).Thanks to apache software foundation for their open source software development & support!
