Solr, the Lucene based Search Server
Solr is a new open-source search server that's based on Lucene, and
has XML/HTTP interfaces for updating and querying, declarative
specification of analyzers and field types via a schema, extensive
caching, replication, and a web admin interface.
It's already in production use at CNET, and has recently been accepted
into the Apache Incubator.
For more information, see Solr's home page at
http://incubator.apache.org/solr/
and the wiki at
http://wiki.apache.org/solr/

FYI, last year when I anounced that CNET was using Lucene, some people
expressed interest (off list) in knowing more about the mechanism used to
manage updates to the index, and cache the individual Filters associated
with each of the options...
http://www.nabble.com/Announcement%3A-Lucene-powering-CNET.com-Product-Category-Listings-p748420.html
Solr is that mechanism.
The pages use a custom Solr plugin to determine all of the individual
Queries to execute based on the category, but Solr's built in Filter
caching and DocSet methods are what make it possible to efficiently
compute all of the Attribute Filter counts. (in Solr a DocSet is an
abstraction representing all documents that match a Query or Filter,
without any scoring or sorting -- like a BitSet returned by a Filter,
except that Solr can optimize small sets into a smaller representation)

Definitely. Solr uses Java5, so it would need to be backported.
People may also be interested in the SynonymFilter Solr uses, as it
can handle multi-word synonyms. I kept that one at a Java 1.4
language level with the intent on contributing it to Lucene.
See the bottom of
http://wiki.apache.org/solr/AnalyzersTokenizersTokenFilters for an
example synonym config file.

Just had a look, quite impressive.
I noticed that you have a WordDelimiterFilter; any chance that this will be
contributed back to Lucene? This class is really useful! (In fact I was
just trying to write something similar myself...)
