Dave Balmain has done a wonderful thing - ported Ruby to Lucene, called . He released it in a very robust, usable, and well documented state. With Rails increasingly becoming the web platform of choice, Ferret is surely a hit.

Erik will be presenting Lucene to the Dallas Java Users Group on Wednesday, September 14.

Lucene expert Chris Hostetter announced, with detailed implementation notes, that CNET.com's Product Category Listings are powered by Lucene. The filtering and caching details are well worth the read.

David Spencer at SearchMorph has just updated his . From the :

I have been collecting URLs to javadoc-generated pages and have updated the index of javadoc trees. Now the Lucene index includes over 162,000 documents (individual pages or URLs) from 630 javadoc trees.

The SIMILE team at MIT recently released Piggy Bank 2.0. Piggy Bank is a very slick semantic web Firefox extension allowing the collection of rich content around the web. What does this have to do with Lucene? The Firefox extension embeds a full Java web server including Lucene for full-text search, as you can see from the Piggy Bank .

Congrats to the SIMILE team!

Jeremy Rayner has ported Lucene in Action's Indexer.java and Searcher.java to Groovy and written a nice little article showing the indexing of some books from Project Gutenberg. Thanks Jeremy!

Wikipedia has started using Lucene for searching. You can read more about it here (check the whole thread), here, and here, plus some nice graphs here.

A 20 minute interview with Doug Cutting about Lucene and Nutch is available on TheServerSide.com.

Erik created a multimedia (slides and audio) presentation introducing Lucene for JavaLobby's Expert Presentation Series. This presentation gives a high-level overview of what Lucene is and touches on important topics such as analysis. Because using Lucene's API is simple, there is enough code shown in the slides to build a rudimentary document search engine.

Update: Erik's project manager, Duane Gran, comments on his java.net blog. Feel free to go directly to the Rossetti Archive search mentioned by Duane.

Erik will be presenting Lucene as part of his Java Gems: Ant, Tapestry, and Lucene seminar at the Greater Boston Chapter ACM on Saturday, April 9, 2005. If you're in the Boston area, this is a real bargain - visit the GBC/ACM site for more details on cost and registration.

For the two local folks that subscribe to these announcements, see you there!

Andi Vajda announced his port of almost all Lucene in Action unit tests and code samples, which means they can now be used with PyLucene.
