Lucene feedback from Atlassian JIRA and Confluence

Mike Cannon-Brookes from Atlassian has posted (some moons ago) two interesting presentations related to Lucene and Atlassian's feedbacks from Confluence and JIRA.

My favorite is the first one: Lucene: Generic Data Indexing. It's a nice introduction to the benefits of Full Text search engines, as well as the gotchas you will face.
I found their use of FilterQuery as a cross-cutting concern implementation for security fairly interesting.

The first presentation also quickly address some of the indexing strategies (synchronous / asynchronous) depending on the product requirements. Mike goes a bit deeper in the second one by describing some clustering solutions and the one they choose.

JIRA has gone very far in its use of Lucene, I am not sure I would have gone that far, but that's definitively a very interesting extreme use case, and very successful :)

Demo of JBoss Seam DVD Store powered by Hibernate Search

Many asked me if the DVD Store demo powered by Hibernate Search that I ran at JavaOne was available online.
The answer is not yet, but it will. My plan is to package it nicely and release it when the beta 2 of Hibernate Search is out.
This will hopefully happen fairly soon. JavaOne being behind us, I can focus back on the code base.

I had some very interesting discussions with some of you about Lucene and the features you need, it's good to see the community growing around the project.

Hibernate Search and JSR-303 at JavaOne

I will be presenting Hibernate Search at JavaOne.

I will be demoing a live migration of the JBoss Seam DVD Store application from a classic SQL based search engine onto Hibernate Search with Google-like search capabilities. If your user pressures you for a decent and useful search feature or your DBA asks you not to kill the database perfs, you might want to take a look at it.

It's Friday at 10h50:
TS-4746 - Hibernate Search: Googling Your Java Technology-Based Persistent Domain Model


I will also give an update on JSR-303 Bean Validation (and Hibernate Validator) about the goals, the expectations and where it fits in the Java ecosystem, with a demo too ;-)

Friday again at 14h50 ( 2:50 PM in our local hosts language ;-) )
TS-4112 - Declarative Programming: Tighten Enterprise JavaBeans (EJB) 3.0 and JSR 303 Beans Validation

See you there
