Short Honk: High Value Podcast about Solr

August 4, 2012

If you are interested in Lucene/Solr and have a long commute, you will want to check out Episode 187 of the IEEE’s Software Engineering Podcast. You can find the podcast on iTunes. Grant Ingersoll, one of Lucid Imagination’s experts in open source search and a committer on the Apache Lucene/Solr project, reviews the origins of Lucene, explains the features of Solr, and covers a range of important, hard to get search information. According to IEEE, the podcast offers a:

dive into the architecture of the Solr search engine. The architecture portion of the interview covers the Lucene full-text index, including the text ingestion process, how indexes are built, and how the search engine ranks search results.  Grant also explains some of the key differences between a search engine and a relational database, and why both have a place within modern application architectures.

One of the highlights of the podcast is Mr. Ingersoll’s explanation of vector space indexing. Even a high school brush with trigonometry is sufficient to make this important subject fascinating. Highly recommended.
