Why Lucene Isn’t That Good | Javalobby
Patches welcome…  I know that is an old saw, but that is the only way it’s going to get better.
There are some good points in here, and some stuff that is a bit dramatic.
We do try to keep adapting Lucene and make it better, but in some respects we [...]

I did a FeatherCast today with Rich Bowen.  Dang, he is quick at editing…

How Rackspace Now Uses MapReduce and Hadoop to Query Terabytes of Data | High Scalability
Nice article on how the Lucene/Hadoop/Solr stack was used to solve a really big problem.  Someday, I hope (when we have actual code),  they can add Mahout to the equation and do even more interesting things with the data.

Coderspiel / January 2008
I hardly think Lucene is creating an isolationist culture, nor do we think our project is perfect.  What we do agree on is that our time is better spent on figuring out how to make Lucene better, not how to spend our time doing UNIX administration in a virtual server environment.  As [...]

Coderspiel / The right tool for the slob
This guy’s comment system wasn’t working at the moment, so I will leave my comment here. This won’t make much sense without reading the post first:
It’s funny you mention Wikipedia as an example, since they are running Lucene. As is Technorati and the Internet Archive. [...]

Lucene: A Tacit Admission of Fail? : ob.blog
If ob.blog gave this post a moment of thought before sharing it with the world, he would quickly realize that hosting a live, 24/7, high traffic site takes more than just some code that one can execute. Perhaps ob.blog is volunteering to donate computing resources, support staff, [...]

Interesting comparison of open source search engines available at http://wrg.upf.edu/WRG/dctos/Middleton-Baeza.pdf.   While it reflects OK on Lucene (hey, we can’t be perfect at everything,) I am interested in finding out more details about what settings were used for indexing.  If they just used the out of the box settings, then I would argue that they need [...]

I have setup a new site to support my Lucene Boot Camp training.  Check it out at http://lucenebootcamp.com.  From there, you can download training setup information, read the class outline, etc.

Lots of good things happening in Lucene land lately, all of which should benefit users with faster indexing and searching capabilities.  Most notably, Lucene 2.3 (hopefully released this quarter) has some major changes in indexing memory management and performance.  I have personally clocked indexing using release 2.2 at about 400 rec/s (single threaded, Mac Pro [...]

Just a friendly reminder, I am giving my Lucene Boot Camp training at ApacheCon Atlanta this year (November.)  Still plenty of time to sign up.  Details on the class are here.  Also, feel free to email me with any questions or things you would like to see.  My apache.org email is gsingers.  I will be [...]
