Lucene in Action

From a lucene-user e-mail list announcement:

SearchBlox is a J2EE Search Component that delivers out-of-the-box search
functionality for fast and easy implementation with your websites,
applications, intranets and portals. SearchBlox uses the Lucene Search API
and incorporates integrated HTTP/HTTPS and File System crawlers, support for
various document formats including HTML, Word, PDF, PowerPoint and Excel,
support for indexing and searching content in 18 languages and fully
customizable search results, all controlled from a browser-based Admin
Console.
 
Main features in this release: 
==============================
- Support for Disk-based search index. Administrators can now choose where
the index is held during operations, In-Memory or On-Disk   
- Preset filter: a pre-defined search query that will be automatically added
to the end-user's search query   
- Indexing performance and stability improvements
- Bug fixes 

SearchBlox is available as a Web Archive (WAR) and is deployable on any
Servlet 2.3/JSP 1.2 compliant server.

SearchBlox is also available as SearchBlox Server. The Server is an
integrated application incorporating everything you need to run SearchBlox.
The Server includes SearchBlox J2EE Component, the Jetty Application Server
and the Java Runtime Environment (JRE) 1.4. With the SearchBlox Server,
there are no additional software requirements to deploy SearchBlox. 

The SearchBlox FREE Edition is available free of charge and can index up to
1000 documents. 

The software can be downloaded from http://www.searchblox.com
