Introduction
Recently, I did some minor work on improving the usability of the Lucene spell checker (see LUCENE-2479, LUCENE-2608 and the associated Solr work) and it got me thinking that a post on spell checking in Solr would be useful.
For those who aren’t familiar, the notion of spell checking in search (often called Did You Mean?) is slightly different from the notion of simply correcting spelling errors. It’s not that we don’t…

Do you remember this scenario from days of yore?
- Company A buys a software license from Company B, a startup.
- Company A crosses its fingers that Company B doesn’t go bankrupt and disappear, along with the source code for Company A’s mission-critical software.
- Company B goes kaput.
- Company A is left with some machine-readable binary code that it is powerless to develop or use.
Source code escrow has changed the outcome of this…

If you missed the SF Bay Area Lucene meetup last night, I thought I would give a recap of some of the highlights. First off, thanks to salesforce.com for the use of their space on the 42nd floor of 1 Market St. in downtown S.F. The views of the bay and the city were especially stunning at night with what appeared to be a full moo
n rising over the Bay Bridge. Salesforce…

As some of you may know, I blog regularly on Network World’s Open Source Subnet. Watch weekly for more of my musings on trends, news and any number of topics that catch my interest. In my most recent post, I ask readers for their take on the legal maze associated with open source. In my opinion, Apache is the most liberal open source package today, the one most true to form. Everybody can use it,…

Back from Berlin Buzzwords and finally over the jet lag, so I thought I would put up some feedback. First off, it was a well organized conference with a nice focus on searching, storage and scaling. Kudos to Isabel, Simon and Jan for all their hard work. It also had great wi-fi coverage, which is always a struggle at every conference I’ve ever been too.
As for the talks, I gave the Keynote on…

The other day, Michael Coté asked me where Apache Lucene and Solr fit in with the NoSQL movement (having heard about the Guardian’s use of Solr), to which I replied: I haven’t used SQL in any significant way since I started using Lucene in 2004 (and I started my career doing Oracle DBA work, etc. way back when.) We just didn’t have a fun name for it “back in the day”.
All kidding…

After reviewing a lot of great talk proposals, we’ve announced the agenda for Apache Lucene Eurocon: Apache Lucene EuroCon – Europe’s Premier Lucene and Solr Search User Conference.
One of the things I really like about this agenda is it is a great mix of basics, use cases from all over the search map (CMS, news, social media, advertising), business decisions (see last list and next list) and advanced topics (NLP, collab filtering, machine…

Apache Lucene (the Lucene top level project, not Lucene the Java search API. I know, it’s confusing sometimes) has once again proved to be a fertile area for innovation (having already given birth to Apache Hadoop a few years back), as it once again has given birth, this time to three new Apache Top Level Projects (just approved by the Board at Apache): Apache Mahout, Apache Nutch and Apache Tika…
