《自己动手写搜索引擎》是猎兔企业搜索开发团队的软件产品研发和项目实践的经验汇总。《自己动手写搜索引擎》全方位展现出一个商用级别的Lucene搜索解决方案，主要包括爬虫、自然语言处理和搜索实现部分。爬虫部分介绍了网页遍历方法和从网页提取主要内容的方法。 自然语言处理部分包括了中文分词从理论到实现以及在搜索引擎中的实用等细节。 其他自然语言处理的经典问题与实现包括：文档排重、文本分类、自动聚类、语法解析树、拼写检查、拼音转换等理论与实现方法。 在实现搜索方面，《自己动手写搜索引擎》用简单的例子介绍了完整的搜索实现过程，覆盖了从索引库的设计和索引库与数据库的同步到搜索用户界面设计与实现。搜索用户界面包括实现布尔逻辑查询、按区间范围查询、搜索结果按日期排序等。《自己动手写搜索引擎》还进一步介绍了搜索排序的优化方法。 最后以基于Lucene的搜索服务器Solr为例，展示了Lucene的最新应用方法。

《Lucene+nutch搜索引擎开发》以Lucene构建搜索引擎的开发过程为主线，由浅入深，循序渐进，为读者展示如何使用Lucene开发自己的搜索引擎系统。全书内容包括搜索引擎概述和原理、Lucene部署安装、Nutch网络蜘蛛与数据获取、Lucene索引建立、Lucene检索与查询、搜索结果排序、文档分析器与中文分词、格式化文本分析、分布式搜索与缓存等。为便于读者理解搜索引擎快速开发过程，《Lucene+nutch搜索引擎开发》最后几章进行了应用实例的讲解，包括Nutch构建专题搜索、Lucene构建企业级搜索实例以及相关的整体工程性能测试。

HIGHLIGHT New edition of top-selling book on the new version of Lucene--the core open-source technology behind most full-text search and "Intelligent Web" applications. DESCRIPTION When Lucene first hit the scene five years ago, it was nothing short of amazing. By using this open-source, highly scalable, super-fast search engine, developers could integrate search into applications quickly and efficiently. A lot has changed since then--search has grown from a "nice-to-have" feature into an indispensable part of most enterprise applications. Lucene now powers search in diverse companies including Akamai, Netflix, LinkedIn, Technorati, HotJobs, Epiphany, FedEx, Mayo Clinic, MIT, New Scientist Magazine, and many others. Some things remain the same, though. Lucene still delivers high-performance search features in a disarmingly easy-to-use API. Due to its vibrant and diverse open-source community of developers and users, Lucene is relentlessly improving, with evolutions to APIs, significant new features such as payloads, and a huge increase (as much as 8x) in indexing speed with Lucene 2.3. And with clear writing, reusable examples, and unmatched advice on best practices, Lucene in Action, Second Edition is still the definitive guide to developing with Lucene. KEY POINTS * Completely revised and updated to current Lucene 2.3 APIs. * Practical coverage, like how to index MS Word, PDF, HTML, and XML. * Full introduction to Intelligent Web topics like smart searching, sorting, and filtering.
