Recently I was puzzled by some behavior Solr was showing me. I scratched my head and called over a colleague. We couldn’t quite figure out what was going on. Well Solr is open source so… next stop – Debuggersville! Running Solr in the Eclipse debugger isn’t hard, but there are many scattered user group posts [...]
I’ve been working in some Python Solr client code. One area where bugs have cropped up is in query terms that need to be escaped before passing to Solr. For example, how do you send Solr an argument term with a “:” in it? Or a “(“? It turns out that generally you just put [...]
For the past year I’ve been talking with Christopher Ball and Erik Hatcher about how frustrating it is to have to carve time out of our regular day jobs to work on Solr and Lucene. Thanks to their enthusiasm for the idea of spending a couple of days hacking on Solr and Lucene, last weekend [...]

These algorithms consumed track data and generated summary data, both of which were stored in Cassandra. The processing engine for [...]
As the “father of the Internet,” Tim Berners-Lee, got onto a plane to head to the burgeoning tech center of Tyler, Texas (all sarcasm intended), he must have wondered how he found himself in this position. Berners-Lee is testifying at a court case of a patent holder who is suing Google, Amazon, and others regarding [...]
Search UIs are getting richer and more interesting by the day. Google page snapshots, animated disclosures of richer data on mouse over, and endless pagination are great examples. Often this type of functionality has a dark side. As each of these features is layered on and integrated with our HTML, it can begin to feel like death by a thousand paper cuts.
Recently, we had a project where we helped a client index a corpus of Chinese language documents in Solr. We have asked Dan Funk, a committer to Project Blacklight to provide a guest blog post for us on the details of how to approach indexing Chinese, particularly when you are a non-speaker. Take it away, [...]
