Lucene in Action, Second Edition, completely revises and updates the best-selling first edition and remains the authoritative book on Lucene. This book shows you how to index your documents, including types such as MS Word, PDF, HTML, and XML. It introduces you to searching, sorting, and filtering, and covers the numerous changes to Lucene since the first edition. All source code has been updated to current Lucene 2.3APIs.

对我而言意义不大。

有一些新特性的介绍，不错。

有些现在已经用上了，比如：MergeScheduler／FieldSelector
IndexReader.reopen()
