The Next Lucene Release

By Mark MillerFebruary 28, 2009

It looks like the next release of Lucene is going to be 2.4.1, a bug fix release. The Lucene release ‘animal’ has raised its head over the previous months on two occasions, once eyeing a 2.4.1 release, then refocusing on a 2.9 release. Time has seen 2.4.1 land a few more bugs than we had though, so it looks like 2.4.1 is in the final wrapup stages and 2.9 will come next.

2.9 will likely …

LuceneMeetupMarch2009 – Lucene-java Wiki.

Lucene users (Solr, Nutch, Mahout, Tika, etc.) are all invited to attend a Lucene Meetup on March 24th in Amsterdam, Netherlands.  Looks like Lucene creator Doug Cutting will be there, as well as some of the other Lucene committers.  I always like these informal gatherings, as they are a great way to share ideas and meet fellow coders.…

Exploring Query Parsers

By Mark MillerFebruary 22, 2009

There are a surprising number of query parser options in the Lucene/Solr world – not something I realized very quickly in my early Lucene days. I thought I might highlight a few of the options out there. …

Drupal.org fires up on Solr

By Mark MillerFebruary 19, 2009

The Drupal.org website was just updated to Drupal 6 and as part of the migration, they are now using the very cool Drupal/Solr integration module and running their site search on Solr with faceting.

I used Drupal quite a bit a few years back, and it was part of a very positive few years of heavy PHP work. I’m happy to hear it has gotten so easy to use my favorite search engine with it.…

acts_as_solr with rich document indexing

By Erik HatcherFebruary 17, 2009

A hearty thanks to the Central Virginia Ruby Enthusiasts’ Group, who invited me to speak on Solr+Ruby giving me a good reason to delve deeply back into solr-ruby and acts_as_solr.

Let’s start a Rails project from scratch to illustrate how simple it is to get up and running with acts_as_solr. The example is, indeed, a fairly real-world’ish type of need. We’re going to index resumes, which could be in standard rich document formats …

Open Source and the Economic Stimulus

By adminFebruary 13, 2009

A number of my peers in the open source community have put together an interesting letter to President Obama on how vital a role open source can play in tackling some of the big challenges we face in this economic climate. In addition to a good set of observations about how the virtues of open source can help the new administration achieve its goals in domains such as health care, they recommend the president make …

Sorting, Faceting and Schema Design in Solr

By Grant IngersollFebruary 9, 2009

I was recently with a client doing a Best Practices assesment when I came across a common source of confusion related to sorting, faceting and schema design.

As background, Solr provides a schema that describes the Fields and Field Types (FT) that are used by an application.  Field Types describe how Solr should handle the information contained in a Field.  For instance, the integer FT tells Solr to treat the contents of any Field of …

Lucene, Solr, Mahout and Droids ApacheCon EU in Amsterdam March 23-27

By Grant IngersollFebruary 9, 2009

Monday, 23 March 2009 to Friday, 27 March 2009

Lucene and me at ApacheCon EU in Amsterdam March 23-27.

I’ve posted a Lucene related event schedule on my blog for people who are interested.  Of particular note are the two days of pre-conference training on both Lucene and Solr.  These are shorter ApacheCon versions of our 3 day training classes.  Obviously, we can’t cover all the material that we do in our full …
